systemd has started mounting a tmpfs in /run/user/<uid> every time a session begins. So after ssh'ing into a box a number of times, dmesg looks like this..
[ 929.892760] SELinux: initialized (dev tmpfs, type tmpfs), uses transition SIDs [ 4529.025836] SELinux: initialized (dev tmpfs, type tmpfs), uses transition SIDs [ 8129.170484] SELinux: initialized (dev tmpfs, type tmpfs), uses transition SIDs [11729.313034] SELinux: initialized (dev tmpfs, type tmpfs), uses transition SIDs [15329.471269] SELinux: initialized (dev tmpfs, type tmpfs), uses transition SIDs [18929.613781] SELinux: initialized (dev tmpfs, type tmpfs), uses transition SIDs [22529.759596] SELinux: initialized (dev tmpfs, type tmpfs), uses transition SIDs [26129.890709] SELinux: initialized (dev tmpfs, type tmpfs), uses transition SIDs [26669.001664] SELinux: initialized (dev tmpfs, type tmpfs), uses transition SIDs [33328.937304] SELinux: initialized (dev tmpfs, type tmpfs), uses transition SIDs [36929.064927] SELinux: initialized (dev tmpfs, type tmpfs), uses transition SIDs [40529.178574] SELinux: initialized (dev tmpfs, type tmpfs), uses transition SIDs [44129.301952] SELinux: initialized (dev tmpfs, type tmpfs), uses transition SIDs [47729.424882] SELinux: initialized (dev tmpfs, type tmpfs), uses transition SIDs [51329.287032] SELinux: initialized (dev tmpfs, type tmpfs), uses transition SIDs [54929.563390] SELinux: initialized (dev tmpfs, type tmpfs), uses transition SIDs [58529.857740] SELinux: initialized (dev tmpfs, type tmpfs), uses transition SIDs [62128.992792] SELinux: initialized (dev tmpfs, type tmpfs), uses transition SIDs
What's a good solution to stopping this spew ? printk_once doesn't seem like a good fit, in case someone is doing different labelling behaviours between mounts.
Could we only print it if the mount is being done with non-default behaviour perhaps?
