I see an issue with systemd-197 on one of my gentoo systems.

Encrypted swap doesn't get enabled correctly as mentioned below.

In the git-repo of systemd I read in the TODO-file:

> swap units that are activated by one name but shown in the kernel
> under another are semi-broken

Might that be related to the behavior I see?


I quote my posting to the gentoo-users-ml:

> I always get timeouts as systemd waits for the decrypted 
> mapper-device to come up. Swap doesn't get enabled but when it 
> finally continues to boot I see the valid mapper-device there and
> can "swapon" it manually.

Thanks, Stefan
