[PVE-User] lxc container can't start on a newly added cluster node

[Stoiko Ivanov]

Hi,

just a guess - does the container have an `/etc/fstab` inside?
and does the `/etc/fstab` contain an entry for `/dev/pts`?

If yes - I guess the container would start on PVE 5.3 when you remove
the line (or the complete `/etc/fstab`). This might result in it not
starting on PVE 4.x.

Could you test this?

Best regards,
stoiko
