Well, good to see I am not the only one that can't get the chroot to work anymore. So, I suggest, for the minute, I edit the wiki to explain that the chroot does not work. I am open to suggestions as to what it should recommend? maybe using a full virtual machine? What I have found so far is, using the two attached files, in the following locations: /lib/systemd/system/sshd-mageia3.service /usr/local/bin/setup-cauldron-chroot.sh setup fstab: echo 'none /mnt/chroot/cauldron/dev/pts devpts defaults 0 0' /etc/fstab Then, the chroot sshd can be started, using: systemctl enable sshd-mageia3.service systemctl start sshd-mageia3.service which will start a chroot, but.. it's not ideal.. It sees mount points from the host (/proc/mounts) and of course, processes. The recommended approach according to systemd, appears to be systemd-nspawn. This may be viable, when systemd-nspawn is updated beyond the version in Mageia 2. It does not currently work, because dbus won't start, see bug: https://bugzilla.redhat.com/show_bug.cgi?id=795038. The work around mentioned is not supported in the version of systemd-nspawn that Mageia 2 uses. This looks like it would work for Mageia3.
