I agree.

I have not had this issue with suse, I will investigate soon.

noted. I have never yet tested the systemd patches on anything but
opensuse and SLE12.

One of ceph or ceph-deploy has to change this first. I propose ceph.

rgw does work on suse, but I noticed a bug in the patches you where
working on, I am looking at the other issues, you raise.

https://github.com/SUSE/ceph/commit/08c805c18dd994d7b2c4c521a209bb50310b1bbd


Note mds is some thing I have never tested but have never even used the mds.

Yes I found this too on suse, I think I am near fixing these issues for
suse. Once they are fixed I will once again look at fedora.
