This patch adds a udev rule, so that you can specify
rd.luks.reencrypt=<UUID> instead of rd.luks.reencrypt=<devname>
It also moves the job to the "settled" queue, which means, that it is
executed after udev has settled.
A finished hook prevents dracut-initqueue from exiting and lets it
finish the batched jobs. Without a "finished hook" and without
"root=<dev>" on the kernel command line, the reencrypt job would not be
executed.
Normally you want to reencrypt without a "root=<dev>" on the kernel
command and want to reboot after the reencrypt job is done.
This patch adds the missing "finished hook".
- add loop module to initramfs image
- modprobe loop before reencrypt start
- add rd.luks.reencrypt_keyslot=
- add conflict with dracut crypt module
- drop to emergency_shell after reencryption
