Hi, I am using luks encryption on my whole filesystem, debian squeeze
on an Acer Aspire One.
After upgrading packages this evening, I booted from the new kernel
(2.6.30-2-686): the system did not ask for
the luks passphrase, saying "unterminated quotes error in
/scripts/local-top/cryptroot"
(absolute path for script included in initram image).
I checked the syntax of the script (original path
/usr/share/initramfs-tools/scripts/local-top/cryptroot) with "bash
-v",
and found out that the new script version fails to correctly bash-expand
the kernel cryptopts option you can see below
(cryptopts="target=sda2_crypt,source=/dev/sda2,lvm=wudangshan-root"):
the syntax {$x%=*} in the script gives
$PARAM: "target (uncorrect param because of leading ", correct VALUE)
$PARAM: source (correct PARAM, correct VALUE)
$PARAM: lvm
$VALUE: wudangshan-root" (correct PARAM, uncorrect VALUE because of trailing ").
I stress that the syntax of the kernel command line option did not
cause any problem with previous releases, so
it should be correct, as far as I know.
I made a workaround by adding
if [ "$PARAM" = "lvm" ]; then
VALUE="wudangshan-root"
elif [ "$PARAM" = "\"target" ]; then
PARAM="target"
fi
before line 130 (i.e. before eval export CRYPTTAB_OPTION......)
I recreated the initram image for this kernel and rebooted the system:
the system now boots without any problem.
This works for me because I have this certain order of cryptopts in
the kernel cmdline.: a generic patch
that strips quotes from all the cryptopts is needed, I think.
As far as I know (I checked in the squeeze packages list), the script
I modified is included in initramfs-tools.
I also read the package buglist to check if this bug has been already
submitted, but I did not found anything.
I apologize if I failed to notice a previous bug report concerning this issue.
Best regards,
Pietro
P.S. In the following I cut the lsmod info, that seemed to me to be
uncorrelated with the issue.
