Description:
Are manually luksOpen'ed partitions closed on shutdown by either initscripts or systemd units? As a prerequisite are such partitions first unmounted and then luksClose'ed? If they are not closed, can this lead to data corruption?

Steps to reproduce:
- cryptsetup luksOpen /dev/DEV1 DEV1
- mount /dev/mapper/DEV1 /mnt/DEV1
- forget to luksClose and umount before shutdown/reboot in system terminal
This task depends upon

If anyone wants this fixed, post a patch to the projects ml. We're not going to be working on this.

Do you get this issue with systemd?

Sorry I mistakenly asked for closing because I mixed this task up with another one. The issue is whether anyone can confirm manually luksOpen'ed devices are luksClose'd by systemd now that it's the default and I use it.

If you need volumes closed before shutdown, systemd will do this, initscripts is supposed to, and the ultimate solution would be to use mkinitcpio's shutdown hook.

so, yes.
