Ok, well how about this then.. instead of moving the mounts to Ch 5 like I
suggested in the original report, we instead still do it in Ch 6, but before
entering the chroot? In this way, disruption to current flow of the book is
minimal. We just move "Mounting the proc and devpts file systems" to
immediately before "Entering the chroot environment" and Bob's yer uncle! Of
course, some minor adjustments to the text would be needed and we'd have to:
before the actual mounts.
Ch 5 is still done as non-root. In Ch 6, instead of saying "become root" in
the "Entering the chroot environment" section we just say it one section
earlier. No more red "failed" messages :-)
Anyone see a problem with this approach?
