[Bug 332950] Re: Misleading "cryptsetup: WARNING: invalid line in /etc/crypttab - "

[David Schoen]

This seems to still break in Quantal (12.10) when upgrading from 12.04.

I was getting the "cryptsetup: WARNING: invalid line in /etc/crypttab -
" errors when running update-initramfs (under a live CD because the
machine was completely unbootable).

After following advice from
http://forums.linuxmint.com/viewtopic.php?f=189&t=83763 I started
digging around and in /usr/share/initramfs-tools/hooks/cryptroot and
found it couldn't parse /etc/crypttab if the target field wasn't exactly
the device name that was root was sitting under, e.g. changing it from
"sda2_crypt" (what I believe 12.04 alternative installer set it to) to
"sda2" meant update-initramfs and update-grub both ran without issue and
the machine now boots without issue - seems like some dodgy parsing
going on in that hook?

Bug description:
  Binary package hint: cryptsetup

  When there's no line for the cryptsetup root device, a misleading warning is issued during update-initramfs:
    cryptsetup: WARNING: invalid line in /etc/crypttab -

  I'm attaching a patch that handles this better, by outputting
    cryptsetup: WARNING: Missing line in /etc/crypttab for $target
  in this case.

  I've ran into this when manually doing the "mdadm-cryptsetup-
  lvm2-initramfs" dance, and used another name during "cryptsetup
  luksOpen".
