Understood.

An easy solutions might be to follow symlinks when generating the initramfs. I 
just noticed that /dev/VG/LV is a symlink to /dev/mapper/VG-LV.

Alternatively, one could let cryptdisks warn that symlinks are used, so that 
cryptdisks and the initramfs scripts will behave more similarly and not 
surprise the user.
