Is it possible to replace systemd and run SLED with an alternative such as runit? If not, is systemd viable without other component parts (journald, etc.)? I prefer to have my log files in plain text and not binary. Same with DNS resolution.

I'm looking to start my IT security business again and previously, I had suggested SLED and SLES, due to the fact that I had been using a form of SUSE since it was a small German company with a Linux called S.u.S.E. and trusted both their product and their service commitment.

Kind of related, but not on topic, why was systemd embraced so quickly by SUSE? Was it because SUSE is committed to GNOME?
