Yes, "proc /proc proc rw,relatime,gid=4,hidepid=2 0 0". After running "mount /proc -o remount,hidepid=0" I logged in on a VT and saw a session in the list. (I was wrong about this working on the other system. I'm using the same mount options there and also have 0 sessions, at least over ssh.) Thanks for the quick response. Is this problem already tracked? Any idea why it would happen, given that systemd-logind is running as root? -- Michael
