Talk:Install/Chroot
Chrooting from working system?
From 'Chroot into Funtoo' funtoo suggest invoking:
- cd /mnt/funtoo
- mount -t proc none proc
- mount --rbind /sys sys
- mount --rbind /dev dev
Which if invoked from 4.18.18-gentoo-r1 results in:
dreamon / # emerge Failed to validate a sane '/dev'. bash process substitution doesn't work; this may be an indication of a broken '/dev/fd'.
and `mount`: ON CHROOT mount: failed to read mtab: No such file or directory

Was fixed by invoking chroot based on https://wiki.gentoo.org/wiki/Chroot#Configuration
Probably should be included in the handbook?
