Public bug reported: In 24.10 oracular (this didn't happen in 24.04), it's impossible to connect to a machine before systemd-user-sessions.service is started. This is stricter than having /etc/nologin / /run/nologin / pam_nologin blocking logins, because it also applies to root logins.
systemd-user-sessions waits for things like remote-fs.service, overall this makes it impossible to unlock encrypted partitions remotely or to troubleshoot boot issues without messing with the kernel command line through the boot loader. This is fixed in systemd 256.7. Upstream patch: https://github.com/systemd/systemd/commit/278e815bfa3e4c2e3914e00121c37fc844cb2025 (https://github.com/systemd/systemd/pull/23936) Upstream bug report: https://github.com/systemd/systemd/issues/19264 Can this be backported from 256.7? Or can ubuntu be updated to to that point release?
