Module tty 

tty (teletype) for user-system interaction

This module handles console/TTY setup for containers.

Console setup is done AFTER pivot_root (following runc’s approach). This follows runc’s approach in prepareRootfs():

1. pivot_root is called first
2. Create PTY pair from /dev/pts/ptmx (container’s devpts)
3. Mount PTY slave onto /dev/console
4. Send PTY master to console socket
5. Set controlling terminal and connect stdio

See: https://github.com/opencontainers/runc/blob/v1.4.0/libcontainer/rootfs_linux.go
