Description crusaderky 2008-11-21 13:30:54 UTC

I've got
baselayout-2.0.0
openrc-0.3.0-r1
cryptsetup-1.0.6-r2

I've got an encrypted partition mounted in /dmcrypt, and two symlinks on the system:

/home -> /dmcrypt/home
/root -> /dmcrypt/root

With rc_parallel="YES", if I
- logout my normal user
- login as root
- cd /
- manyally stop services, until lsof | grep /dmcrypt returns zero results
- poweroff

I get the message that service dmcrypt can't be stopped since it is in use.

If I disable rc_parallel, everything works fine and the dmcrypt service is stopped correctly.

I patched the stop script to gather some intel:

+		lsof | grep /dmcrypt > /var/log/dmcrypt-fail
 		${csetup} remove ${target}
 		eend $? "Failed to remove dm-crypt mapping for: ${target}"
 	done


After restarting, I got:
$ cat /var/log/dmcrypt-fail

that is, zero processes accessing that partition.
