Description:
Symlinks in /dev/disk/by-uuid are missing when the partitions are in a lvm in luks and are mounted in the initrd.

The missing symlinks are exactly from those partitions, which get mounted in the initrd during boot. These partitions reside in a lvm in a luks partition (for more details of the partitions look below).
After entering my password the luks partition gets successfully opened and also the lvm partitions all get activited and mounted, but no symlinks in /dev/disk/by-uuid are created.
The other lvm in luks partition (home), which gets mounted via the /etc/rc.sysinit (/ crypttab) is mounted fine as well, but the symlinks are created this time.

This behaviour is relativly new, not long ago everything worked as expected.
