I often want to mount a system in a chroot; I often forget all the specifics, and just end up Googling them to try and make sure I don't forget anything. ``` lang=bash # First, mount the system as, say sudo mount /dev/sda4 /mnt # Then these are the bits from your running Linux system you need to mount into the chroot mount -t proc proc /mnt/proc/ mount -t sysfs sys /mnt/sys/ mount -o bind /tmp /mnt/tmp/ mount -o bind /dev /mnt/dev/ ``` Or a more elegant and complete approach: ``` lang=bash sudo mount /dev/sda1 /mnt for name in proc sys dev; do sudo mount --bind /$name /mnt/$name; done sudo mount --bind /etc/resolv.conf /mnt/etc/resolv.conf sudo chroot /mnt/ /bin/bash ``` External documentation: * https://wiki.debian.org/RescueLive
