This looks pretty OK actually. With this setup (i.e. where /dev/tty0 does not exist) it seems entirely unnnecessary to mask the getty services or anything, as they contain a condition (as mentioned) that skips them if this device node does not exist. > LXC (ls -alh /dev) > crw-rw---- 1 root tty 136, 18 Feb 10 07:15 console > lrwxrwxrwx 1 root root 11 Feb 10 07:15 core -> /proc/kcore > lrwxrwxrwx 1 root root 13 Feb 10 07:15 fd -> /proc/self/fd > crw-rw-rw- 1 nobody nogroup 1, 7 Feb 9 08:32 full > srw-rw-rw- 1 root root 0 Feb 10 07:15 log > drwxrwxrwt 2 nobody nogroup 40 Feb 10 07:15 mqueue > drwxr-xr-x 2 root root 40 Feb 10 07:15 net > crw-rw-rw- 1 nobody nogroup 1, 3 Feb 9 08:32 null > lrwxrwxrwx 1 root root 13 Feb 10 07:15 ptmx -> /dev/pts/ptmx > drwxr-xr-x 2 nobody nogroup 0 Feb 10 07:15 pts > lrwxrwxrwx 1 root root 4 Feb 10 07:15 ram -> ram1 > crw-rw-rw- 1 nobody nogroup 1, 8 Feb 9 08:32 random > lrwxrwxrwx 1 root root 8 Feb 10 07:15 shm -> /run/shm this looks wrong... > lrwxrwxrwx 1 root root 4 Feb 10 07:15 stderr -> fd/2 > lrwxrwxrwx 1 root root 4 Feb 10 07:15 stdin -> fd/0 > lrwxrwxrwx 1 root root 4 Feb 10 07:15 stdout -> fd/1 > crw-rw-rw- 1 nobody nogroup 5, 0 Feb 10 18:17 tty > crw-rw---- 1 root tty 136, 0 Feb 10 07:15 tty1 > crw-rw---- 1 root tty 136, 1 Feb 10 07:15 tty2 > crw-rw---- 1 root tty 136, 2 Feb 10 07:15 tty3 > crw-rw---- 1 root tty 136, 3 Feb 10 07:15 tty4 Urks. This looks super wrong. A container has no VC subsystem, and these devices really shouldn't exist there. /dev/tty1, /dev/tty2 and so on are the interface to the Linux kernel VC subsystem, and nothing else. > drwxr-xr-x 3 root root 60 Feb 10 07:15 .udev Wut? where does this come from? the last time udev used that directory was 4 years ago or so...
