Something like > > chvt 6 > /bin/bash -i </dev/tty6 >&/dev/tty6 Well vt 6 is where the installer X server seems to run but yes. I'm afraid I copy openvt onto the box during %pre so things in %post (etc) can use it - it is a cleaner tool. (note that the sl5 busybox includes an 'openvt' but that doesn't have the useful options). In the %post remember that the startup scripts havn't been run so files like resolv.conf may not have sane contents. We use "%post --nochroot" so we can first copy bits of state (stuff we saved from any previous install, the ks files and logs from the install) into the newly installed tree, and then mount a directory from which we run various scripts in the chrooted tree: ... # location of new root NR=/mnt/sysimage ... ## Get dns lookups working enough to do the first mount (sigh...) cat > $NR/etc/resolv.conf <<EOF ..... <put your contents here> .....
