I just chrooted to BL3 partition and ran rc and I can now also run links2 
and startx.  inittab refers to rc, sets up three tty's with sh (did I 
already do that with chroot /hd /bin/sh? - if not, bash from BL2 is fine), 
sets Ctrl-Alt-Del to reboot, and does shutdown and restart.  Since I think 
these are the same in BL2, it should be enough just to run rc in order to 
access BL3 in a BL2 terminal.  Could I type chroot /hd /bin/sh;rc and make 
this an alias called bl3?  Then I could run netpbm and playmidi and 
abiword in BL3 after booting to BL2.  My partner wants to run dosemu from 
BL2 but the latest version (maybe there is now a later one) had a CLI bug 
(no A or S).  I would rather not be mixing libc5 and libc6 libraries 
(libpng, for instance) in BL2.  It would be lovely to have them on 
different vts.


rc sets the BL3 path, and runs e2fsck on the new partition.  I could 
instead of rc use the PATH line in rc.

In BL2 rc sets the path to /bin:/sbin:/bin/busybox.
In BL3 to /sbin:/usr/sbin:/bin:/usr/bin - why not busybox?

/etc/profile also sets the path - in BL3 it adds /usr/X11R6/bin and 
/usr/local/bin.  In BL2 it adds /usr/local/sbin, /usr/X11R6/bin 
/bin/busybox.  (I may have added the /usr/local/sbin myself).

Should I also be running profile or does chroot do that?

No need for that any more but I can try it some time.

What is a Bitkeeper fiasco?

I will try setup from within FE in case I forgot to try that.  I think I 
tried to setup from DOS or boot from the SE CD.
