I just noticed that on SLES 11 SP1 if you run dracut -f one of the last things it says is Stored kernel commandline: and it includes rd.lvm.lv=system/usr
(system is our VG name) SLES 12 SP2 does not include that. So yea, it would be good to get SUSE's opinion. Is this intentional or a bug?

Indeed I have seen some other dependencies that do not work well without /usr mounted during boot. For instance in SLES10/SLES11 the /etc/init.d/boot.rootfsck (or rather /sbin/chkconfig) depends on /usr/bin/perl but with a separate /usr this is not available at that point. The /usr is to be mounted only after the root filesystemcheck. But I do wonder, there are a lot of shops that use a separate partition for /usr so I would expect to have seen more about this. In our linux group they use the separate /usr setup and we have to take their defaults. In fact, their default setup has been changed recently so I would have expected them to change this setup if that would have been identified as a problem. The page at freedesktop refers mostly to Fedora. It also links to another page (https://www.freedesktop.org/wiki/Software/systemd/TheCaseForTheUsrMerge/) that talks about moving /bin and /sbin into the /usr/* counterparts, once again referring to Fedora. Also these pages mention that having /usr on a separate partition is still supported. But is it? The point I have seen is that initramfs should mount /usr during early boot but it looks like it's not working correctly as an attempt is made to umount it by systemd. @Mark Post, What is the position of Suse in this matter? Is Suse also working towards moving the /bin and /sbin to /usr/*?

Anyway, with systemd you are actually discouraged from maintaining a separate /usr filesystem, details here: https://freedesktop.org/wiki/Software/systemd/separate-usr-is-broken/ In a nutshell: I have given up and keep /usr in my root filesystem now.
