Hi Marek,

Acked-by: Nicolas Ferre <nicolas.ferre@atmel.com>

BTW, isn't it something else required to run a systemd enabled image?
I've seen that some of the option may be missing as well:

CONFIG_FHANDLE (libudev, mount and bind mount handling)
from: https://github.com/systemd/systemd/blob/master/README#L51

In the " Optional but strongly recommended:" I see interest in:
 CONFIG_AUTOFS4_FS
 CONFIG_TMPFS_XATTR
 CONFIG_{TMPFS,EXT4,XFS,BTRFS_FS,...}_POSIX_ACL

But it's maybe not so interesting for our little embedded systems.

I'm also puzzled about the need for more options about cgroups...

I add a couple of other people in Cc so we can figure out the proper
configuration set...

Thanks Marek for having started the discussion, bye,
