Bugzilla Bug 90053

This is the meta-bug for Project Dolphin. Everything related to the iso-image
should go HERE AND NOWHERE ELSE

Reproducible: Always
Steps to Reproduce:

enhancement request #1... ;]

Make sure you document that ALL bugs go HERE on the CD itself, in a README in the download directory, and as the friggin' splash background, if need be.

Request #2: net-misc/rdiff-backup on the CD would be _way_ cool. But please no
testing versions (0.13.x).

request#3: net-misc/rsync

roger

Request #3: app-admin/testdisk-5.6

I've found this to be an indispensable tool for recovering a lost partition table.  It'll scan your disk for remains of old filesystem tables, allow you to browse old filesystems through it without mounting them (or even having them in your partition table) and will rewrite your partition table on request.

I would find the following features useful:

1. rsync
2. A very light X support with a simple desktop manager e.g. Fluxbox (like Insert Live CD based on Debian)
3. Mozilla Firefox

in response to comment #5, i do not believe x11/WMs are necessary. to my
knowledge, the purpose of this project is rescue _only_. you shouldn't need x11
to rescue...

if you are trying to research your problem, then either use knoppix or another
computer

</imho>

I have a Dell X200 Laptop.  Its CD rom (in the docking station) uses firewire
to connect to the PC.

Under gentoo I need to load a few ieee1394 modules, and then the cd gets mapped
to a scsi device.

When I boot the Dolphin cd, it seems to be loading some firewire modules (text
scrolls by too quickly.)

Then I get some error messages

Attempting to mount CD
/newroot/dev/cdroms/*
/newroot/dev/.....
etc.

Then

could not find CD to boot
something else needed.

The shell that I can then load seems too raw to give me any more info.

Hope this helps.

Does it have Reiser4 support? I know it's controversial, but being a rescue cd,
it should support as many file systems as possible...

enhancement request: amd64 version, with gcc 3.4.x & distcc

re comment #5: For now, X is not considered to be on the livecd since it is not
needed to use the tools on the cd and there are no X-only rescue-tools.

re comment #7: This is a very ugly bug we mostly experience on Dell-Hardware
(but not only on Dell-HW). We know of it, but aren't able to solve it at the
moment (since we don't even know *what* causes this bug)

re comment #8: As long as Reiser-4 is not part of the plain vanilla kerneltree,
it won't be added to this (and any other) live-system.

re comment #9: I will give our amd64-guys a call. Lastly, it is their decision
if they are going to jump on the boat or not. Remember, this project is
expeirmental and nothing considered to be released regulary.

support for reiserfs in parted would be good too.

Two things:

1) I'm getting an error with the bootsplash where silent splash actually locks up, causing the progress bar and icons not to work.  I know this is probably not a priority, but I get this error with the live-cd splash theme in general, and I you guys might want to know about it.

2) The hardware detection appears to be a little messed up.  With the 2005.0 live-cd, my sound card is correctly detected, and the appropriate alsa module is loaded (snd_intel8x0).  However with Dolphin, it says it can't tell what soundcard I have and proceeds to load all the alsa modules (thats alot of kernel modules).

3) Just a question. In the 2005.0 live-cd specs, it lists both ipw2100 and ipw2200, but these packages block eachother.  Are both on this live-cd? And if so how did you get around the block?

Well it seems my two things turned into three things, oops. Anyway, to add
something in addition to my previous comment, the splash bug appears
sporadically, in that sometimes I will boot and the progress bar will move
across the bottom of the screen, and various icons will appear in conjunction
with the boot process, and other times nothing will happen at all.  I've talked
to several other people who have had this problem with the 2005.0 live-cd and
live-cd splash theme, so this at least is not isolated to me.

sys-fs/dd-rescue

this is an invaluable tool when you need to recover data from a failing drive.

It may be worthwhile to combine the Gentoo/Linux portion of the LiveCD with
FreeDOS-based applications (which work well with strange setups much better
than Linux can currently).  See http://www.ultimatebootcd.com/

I recently used a combination of the Ultimate Boot CD (to rebuild a partition
table from a Windows Server 2003 LDM and rebuild NTFS indexes), to perform
tasks which Linux could not do.  Once that was complete, I booted into a Gentoo
Universal CD, mounted NFS and NTFS, and copied files from the bad drive.

sys-block/partimage
sys-apps/parted
sys-block/disktype (invaluable when identifying Macintosh partition structures)

Some form of memtest86 as well as other physical stress tests (HDs, etc.) would
be handy.

Also, as many app-forensics apps as you are willing to stuff in. ;)

x86-64 support is less of a priority, at least to me, despite the fact I use a
lot of amd64 hardware.  All 64-bit hardware I use has full 32-bit support.  The
goal, IMO, of a rescue/live CD is to run on as much hardware as possible -
compilation optimizations for 386+ should be the target early on.

There is a possibility for a great deal of convergence here, with the
FreeDOS-based applications, Dolphin, and Pentoo (intrusion detection LiveCD). 
There is no reason I need to boot a system three different times to fix one
machine if all of these tools are combined.

memtest86 is already there.  See the boot help screens for instructions on how
to launch it.  

I'm also experiencing the ALSA bug with snd_intel8x0.  Also, no default mixer
state is in place... should one be added?

Make it fit on Business Card CD. Pre-burnt, I'll take a few.

One thing that the gentoo project as a whole is currently lacking, would be PXE
(aka network) booting. For those of you who don't know what this is, the
process is simple.

1) Client runs PXE ROM, these days every mobo with an integrated NIC can do it
(specify the intel UNDI as boot device)
2) Client runs DHCP broadcast, receives an IP, TFTP server IP and file to
download
3) (Typically,) pxelinux is run, which grabs a kernel and an initrd off of
TFTP, and then executes them as a normal boot.

If the point of this is a rescue CD, I can think of no better, rather unique
addition, than the ability to walk into a room, and without even touching a
medium, have a copy of this running.

As I said, only a kernel and an initrd can be grabbed via TFTP... which leaves
the actual root filesystem still. After poking around the initrd, the needed
changes would be trivial to add another source to the start scripts. There are
a few blocking issues though, that should be easily resolved.

1) To mount (SMB, NFS, anything supported by the kernel to get to the root
filesystem), you need an IP... this means that either A) the kernel has support
for the NIC built-in (non-module), support for auto IP config via DHCP is
compiled in also (and ip=dhcp added to kernel boot line), or B) The init script
loads all needed network modules, runs dhcpcd, and then mounts the needed
filesystem.
2) The init scripts need changing to support another medium other than
CD-ROM... I'd poke further, but I'd like to see what kind of support this has
before I poke further. It looks like the base system is already there, it just
needs to be added to.

I think that this would be an awesome feature to add to this CD, and then if
there is enough interest, changes would be minimal to port this to gentoo
release. People have been saying, "die floppy, die!" for a bit now, but I'm
already moving on to the "die CD-ROM, die!" stage ;).

Again, if I could get this feature added, or if anyone cares enough, I'd be
more than willing to help get this added, and possibly ported to other gentoo
projects. 

The spec files used to create Dolphin should be posted.  This would help
everybody during the creation process better understand how Dolphin works and
is put together.

------- Additional Comment #11 From Carlos Silva  2005-04-26 15:51 PST -------

support for reiserfs in parted would be good too.

Well ... the patches that allow parted to use reiserfs are buggy beyond measure. That way lies filesystem corruption ... exactly what you **don't** want on a rescue CD. I gave up on reiserfs because of that.

*** Bug 91067 has been marked as a duplicate of this bug. ***

From 91067:  Add dump & restore

From 81403: Add gpart

Project dolphin badly needs nfs / smbfs support.

It's really surprising that the rescue CD lacks support for NFS since its a crucial way to rescue data.

The programs listed below are all commandline utilities that I use when
repairing a PC with linux or windows on it.


sys-fs:
-----
ntfsprogs
reiserfsprogs
dosfstools
ext2resize
lsscsi

app-forensics:
-----
rkhunter
memdump

net-wireless:
-----
wireless-tools

sys-apps:
-----
file
pciutils
x86info

app-arch:
-----
tar
bzip2
gzip

I would suggest some minimal network testing support if we need to rescue data
over the net
net-analyzer/nmap

And a great set of tools for data forensics
app-forensics/tct

Perhaps a simple script that dumps itself on a partition and makes it possible
to boot? The sysresccd has the ability and I find it quite usefull for
non-Linux systems to have a rescue partition (quite small) with partimage or
the likes on it. Especially since it's used for systems that don't have a
cd-rom (they do support USB CD-ROMs which we have).

New Image -r2 has just been created; I will have infra moved it out to
experimental, soon.


Adds:
-----
I added all of your suggestions, except some packages because they were either
broken (i.e. won't build) or were marked ~arch.


Bugs: 
-----
I can't reproduce the snd_i8x0 Bug. The Kernel-config and the layout of the CD
is the same as 2005.0 so it normally should work. Drew, can you give some more
information, please?

Dell-Problems: General problem, not only, but mostly seen with Dell-Computers.
Working on it also in the regular releng-work.

I was sad to see after downloading -r2 that dump & restore are still missing...
Did they just fall off or is there a problem with them?

Thanks,

Kailee.

Eagerly awaiting a 2005.1 version!  (ie, 2.6.12 kernel, dmraid support)

With the current (2005.0-r2) cd, having pdcd202xx_new compiled in statically
means that you can't use the pata_pdc2027x.ko module to access Promise
PATA-based raid images.  And since dmraid is currently missing....

Re-assign.
