ENTER-CHROOT(8) System Manager's Manual ENTER-CHROOT(8)

enter-chroot — open a shell in the installed system

enter-chroot mountpoint

enter-chroot mounts what a running system needs into mountpoint (/dev, /dev/pts, /dev/shm, /proc, /sys, /run, /tmp and, on UEFI machines, the EFI variables), then starts a login shell there with chroot(8), so the new system's /etc/profile applies. When the shell exits, everything it mounted is unmounted again.

The EFI variables are what efibootmgr(8) needs to add a boot entry.

# enter-chroot /mnt

bootloader(7), installation(7), chroot(8)
