Re: [systemd-devel] Root remaining read-only after boot, no obvious reason why

[systemd-devel] Why does stopping mount units kill user sessions?

Hi, after Don gave me the hint about the automounter problem in the other mail I still didn't understand why stopping a mount unit should kill the user's session, so I tried that manually. And indeed, with :/b /home/b nfs4 defaults,noauto,x-systemd.automount 0 0 in /etc/fstab, /home/b will be

Hmm, so we stopped enabling systemd-remount-fs.service in this way back in 2018 (https://github.com/systemd/systemd/commit/9b69569d2c). At this point, that's ancient history for us ;) We're unfortunately stuck to the RHEL 8 choice for systemd, yeah... ancient for sure. One step I haven't taken i

[systemd-devel] idle home NFS gets unmounted although user is still logged in

Hi, we've a problem with a user session getting killed by systemd although it shouldn't as far as we understand. We have a jupyterhub running on a SLES 15 SP4 server. When a users logs in (widh pam) and starts a server (which is just a jupyterlab process), jupyterhub spawns this server with sudo
