Enable CGROUPS support, so we can boot userspace that uses systemd on
top of kernel configured using this defconfig. The systemd userspace
depends on cgroups and without them, it dies in mysterious ways.

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,

This one is absolutely mandatory, but this is also enabled by default
already. Debian testing with systemd won't boot without FHANDLE too,
so this is easy to trap for me.

Hm, these are disabled, but I cannot comment on their significance.
> I'm also puzzled about the need for more options about cgroups...
Enabling CONFIG_CGROUPS is enough to make systemd happy and booting.
I didn't probe further, sorry.

CONFIG_FHANDLE is listed as a mandatory kernel option for systemd. So
explicitly enable it to allow easy use of systemd userspace.
Reported-by: Marek Vasut <marex@denx.de>

Hi Marek,
It seems that on my side, CONFIG_FHANDLE is not selected automatically...
So I add this patch: can you tell me your thoughts?
Bye,
Nico.

Absolutely. The patch f76be61755c5 ("Make CONFIG_FHANDLE default y") has
been added in v4.6-rc2... while I was doing my tests on at91-next that
is based on v4.6-rc1 :-\
Anyway. It's in now. Thanks,
Bye,
Nicolas
