Bug 107667 – sys-kernel/genkernel-3.3.6 linuxrc/initrd.scripts needs clearly defined usb keychain media support

• Status: RESOLVED INVALID
• Product: Gentoo Hosted Projects

[Description postmodern 2005-09-29 20:55:44 UTC]

Currently the linuxrc/initrd.scripts script supplied with
sys-kernel/genkernel-3.3.6 detects and accesses usb keychains (residing at
/dev/sd*) in the same way as cdroms. This is incorrect since usb keychains are
obviously not CDs making all diagnostic messages relating to CDRoms seem out of
place when your booting off a keychain. Also USB keychains are not read-only
material and should not be mounted with the -r option by default.

A findcdmount like function that caters to usb media should be created so that
USB keychains are treated appropriately and users building Gentoo enabled
keychains do not have to hack the scripts themselves. A sample of such a
function is attached.

Reproducible: Always

sample findusbmount function

A sample of a findusbmount function, similar to findcdmount but caters to usb
media.

Perhaps this instead?

[Comment 3 postmodern 2005-10-01 17:56:14 UTC]

Ah yes much better. I'm about to slap Gentoo on my new Corsair usb keychain with
some modified linuxrc/initrd.scripts that implements USBROOT and USBROOT_DEV
keywords that enable CDROOT but gives preferrance towards findusbmount in the
bootstrapCD function. I'll post the patchs after it's all tested.

patch to linuxrc for usbfs and usbroot

Adds the kernel command line option usbroot which is similar to cdroot, but
enables the mounting of usbfs and causes bootstrapCD to use findusbmounts
exclusively.

Any reason for the "else" in the "if [ "${CDROOT}" -eq '1' ]" section in
findusbmount()? As far as I can see if we have usbmount we always have CDROOT
too. Also is the usbfs needed for something (such as mounting a USB key, for
example?) as I just see it getting mounted and then later unmounted. Patch looks
great otherwise, thanks!

*poke* (See comment #9)

[Comment 12 Chris Gianelloni (RETIRED) 2006-04-13 08:45:12 UTC]

Is this even necessary?  I'm just not sure I understand why we need specific USB handling, when using the CD stuff works perfectly for USB keychains?

[Comment 13 postmodern 2006-04-13 16:46:14 UTC]

Alright then, I havn't worked on this in a while so it's probably been fxied long ago.
