Package: initrd-tools
Version: 0.1.82
Followup-For: Bug #303403
I have reproduced the bug with kernel 2.6.12-1-686 with a RAID
setup. I have also found a workaround.
The system has both root and a swap partition on RAID1. The swap
partition is ecnrypted with a random key, but the root partition
isn't.
In /etc/crypttab I have the following line:
---------------------------------------------
swap /dev/md1 /dev/random swap
---------------------------------------------
In /etc/fstab I have among other things:
--------------------------------------------------------
/dev/mapper/vg0-root / reiserfs acl 0 1
/dev/mapper/swap none swap sw 0 0
--------------------------------------------------------
I should add that vg0-root is an LVM partition on /dev/md2.
The /script generated by mkinitrd for this setup contains an
unnecessary call to cryptsetup, and some cruft which mentions the swap
partition. This is all totally wrong and causes the pass phrase
prompt. (See attached file "script.bad".)
(Note that this script is generated even if the swap partition is not
activated, as long as it is configured in /etc/crypttab and
/etc/fstab).
If I remove the swap lines from /etc/crypttab and /etc/fstab and run
"dpkg-reconfigure linux-image-2.6.12-1-686", a different /script
is generated (see "script.good"). This one does not call cryptsetup,
and there is no pass phrase prompt.
Finally as a workaround I can set
ROOT=/dev/mapper/vg0-root
in /etc/mkinitrd/mkinitrd.conf (instead of the previous setting of
"probe"), and this way mkinitrd does the right thing even if the swap
is activated.
I also have a second system where the swap is encrypted, but with both
swap and root on a normal partition (no LVM or RAID). On this system
the bug does not appear at all.
