Description

I'm use a gentoo with no systemd.
If I run ceph-volume lvm activate --all --no-systemd, I got this:

--> Absolute path not found for executable: systemctl
--> Ensure $PATH environment variable contains common executable locations

systemd is a hard dependency for this to run. How are you planning on managing the OSD daemons without it?

The activate_bluestore and activate_filestore functions can run without systemd.

What would be the problem to not check whether the daemon is running?
As I see it, the activate functions don't check if the daemon is running and it looks they can handle that the daemon is already running.
