Fix Debian 11 bullseye slow SSH login and sudo on LXC Proxmox

# If Debian 11 is ran on a LXC container (Proxmox), SSH login and sudo actions can be slow
# Check if in /var/log/auth.log the following messages 
Failed to activate service 'org.freedesktop.login1': timed out (service_start_timeout=25000ms)

-> Run  systemctl mask systemd-logind
-> Run pam-auth-update (and deselect Register user sessions in the systemd control group hierarchy)

it works, thank you

This fixed my problem, thank you.

It's not possible to enable nesting in privileged containers though.

It's possible to turn on nesting after container creation: CT |-> Options |-> Features |-> Edit

Thanks! 🤗

Basically there is no need to mask the systemd-logind service. Just turn on "nesting" in proxmox.

This worked. I had forgotten to turn this on when I created the LXC.

Thank you, man
