Ah, so you may also know the solutions for my issues below, from a
Google+ post a while ago?

Thanks ;-)

So far I tried to stay out of the systemd discussion...

While dist-upgrading my debian-armhf/jessie NFS roots, systemd was
installed on one of them, breaking the next boot of the affected board
:-( Interestingly (or rather: fortunately), only one of them got
systemd, the others are still alive and kicking with sysvinit-core.

Failure 1:
systemd[1]: Failed to mount tmpfs at /sys/fs/cgroup: No such file or directory

Ah, let's enable CONFIG_CGROUPS in the kernel.

Failure 2:
A start job is running for dev-ttySC4.device
Timed out waiting for device dev-ttySC4.device

Bye bye serial console :-(

Seems this needs CONFIG_FHANDLE.

Failure 3:
Hey... I seem to have a working system again? Is this too good to be true?

Yes it is:
3.1. Autologin on a serial console is no more. I tried to enable it,
but couldn't get it to work (the agetty is started automatically,
based on the kernel's console, without the help of any config file in
3.2. "stty rows N" doesn't seem to have any effect on my serial console anymore?
3.3. My root filesystem stays mounted read-only.

Fortunately sysvinit-core is only an apt-get install away...
