This is more out of interest than necessity but I'd like to know where systemd-logind.service stores its persistent data. E.g. in particular when I run 'loginctl enaable-linger chris' where is the required flag set?
It must be a persistent location as 'enable-linger' obviously survives a reboot, but I just can't find where it is. There is a sort of reason for wanting to know this, I want to backup the information so that if/when I rebuild a system it doesn't get lost. At present I just have a note to myself in my configuration repository that 'loginctl enable-linger chris' needs to be run on a couple of systems but it would be nicer if I could automate it. -- Chris Green ยท
