Bugzilla Bug 177100

As requested in
http://www.mail-archive.com/gentoo-dev@lists.gentoo.org/msg20846.html, I'm
attaching patched scripts for mounting dmcrypt swap and other encrypted
volumes.

Sadly it still can't be started after urandom, because it must be started
before checkfs (and apparently checkfs won't start properly if urandom is
started before it).  Sorry...  5:(  It may eventually be possible with multiple
start-up services, such as one for swap, one for pre-lvm and one for post-lvm. 
That should allow urandom to be started after checkfs, but before the
dmcrypt-swap starts, since swap doesn't need to be checked.

Anyway, the new rcscript is called dmcrypt (to try and stay in keeping with the
addon name).  To stick with the "/etc/init.d/name means /etc/conf.d/name" idea,
/etc/conf.d/cryptfs has now been changed to /etc/conf.d/dmcrypt.

Finally, I've only really tested this with swap, but it appears to work.  Hope
it helps/is a start...  5:)

It also fails to mount lvm volumes. My /dev/vg1 symlinks are never created. I
can manually mount the files in /dev/mapper after boot. 

If this is unrelated, please let me know and I will file a separate bug.

Hiya Jose, sadly that is unrelated.  Baselayout-2 now requires each of the
volumes type (lvm, raid, dm-crypt, etc) to have their own init script and this
one only covers dm-crypt.  You can read more about the decision at
http://www.mail-archive.com/gentoo-dev@lists.gentoo.org/msg20842.html.

Jose, it appears you're after bug 175983.  5:)

Created an attachment (id=118221) [edit]
/etc/init.d/dmcrypt rcscript - version 2

Slightly corrected rc-script that removes dependencies for baselayout-1 (as
yoinked from bug 175983) just to be on the safe side, and also now shuts down
the dm-crypt stuff as well...

Thanks very much, I'll follow that bug instead.

Created an attachment (id=119463) [edit]
/etc/init.d/dmcrypt rcscript - version 3

Slightly fixed up version that now includes a stop function (because otherwise
dm-crypt-stop.sh is a bit pointless, I'm not sure why I didn't include one
initially) and also fixes an issue in the warning for baselayout-1 users that
was using a baselayout-2 variable, pointed out to me by Hoffie.  5:)

Any news on this bug? Now that baselayout-2 is on the horizon...

And please change summary to "sys-apps/baselayout-2.0.0_rc2 no longer loads
dm-crypt volumes".

in cvs. make sure you emerge cryptsetup and NOT cryptsetup-luks. You'll also
have to do the "rc-update add dmcrypt boot" etc.

ok. Thanks. BUT the addons scripts should search
for the cryptsetup binary in /sbin and not in
/bin/cryptsetup...

then everything is working fine again.

yeah i fixed that in cvs the day after, just remerge to get the correct /sbin
reference.
