Well, I do not want to do that for a single reason:
SSSD is unfortunately still buggy enough to go offline (at least chances are high) when
machine is restarted.
With tmpfs, my automouter would be busted that way and several serviced would not start
Luckily enough, there is still an option to mount it via NFSv3. That way, even if sssd
goes offline, it still has sufficient data in cache for automounter to start properly.

Simo or other more seasoned Samba developers might know better, but
IIRC tdb (the underlying key-value store our ldb cache uses) wasn't
usable well on NFS due to some locking issues..
So the solution/workaround is to mount tmpfs on /var/lib/sss/db/ on diskless
