you could run aif -p interactive -l and change relevant debug calls
(eg those in process_filesystem) to log calls.

it definitely should. why do you doubt this? (you see that aif exists, after spawning the error,
you see. try -l then

the fact that it's a symlink, is by itself not a problem:
$ ls -alh /dev/mapper/cryptpool-home
lrwxrwxrwx 1 root root 7 Apr 10 08:28 /dev/mapper/cryptpool-home -> ../dm-3
$ [ -b /dev/mapper/cryptpool-home ]
$ echo $?
we first of all must be sure that $1 is what we expect. so put a log call as the very fist thing
in process_filesystem that logs "$@"

it should. process_filesystems is designed to do them in correct order (this is
why it's very useful to change the debug calls to log calls, then you can follow which devices it does)
each process_filesystem call is definitely synchronous btw. ie. the function runs as long as the mkfs/cryptsetup/.. is running.

thank you. this is definitely needed.
