Debian Bug report logs - #671037
can not change target name of root in /etc/crypttab

Package: cryptsetup
Version: 2:1.4.1-3
Severity: important

Hi,

I use LVM over LUKS, I got the warning below when I run
`update-initramfs -u` after the target name changed.

cryptsetup: WARNING: invalid line in /etc/crypttab for sys -
cryptsetup: WARNING: invalid line in /etc/crypttab for sys -

And reboot failed(BTW, `ln -s /dev/dm-0 /dev/mapper/NEWNAME` dosen't
work).

Yes, I found a way(by which I changed the name from sda2_crypt to sys
and successfully boot):

0, enter another system(like livecd)
1, luksOpen with the new name, change the target name to the new one
2, chroot into it(now, the living target name is the same as it in conf)
3, update-initramfs -u
4, reboot

IMO, the func "add_device" in /usr/share/initramfs-tools/hooks/cryptroot
should not get root options from target, it should get those options
from source.
