I have a plain Manjaro-only install with FDE.
I am concerned with every reboot, what do I do if something goes wrong. With an unencrypted disk worst case I can do a full reinstall and get the data from the old disk.
Would I need to backup some encryption key if something goes wrong and I would like to read from my original disk with another/new install ?
Where can I find any resources what to do if something goes wrong (i.e. encrypted disk gets corrupted) ?
