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),

chroot runs the specified program (/bin/sh) with the specified root
directory (/hd) in the current tty for most programs (includes sh).

Could I type chroot /hd /bin/sh;rc and make this an alias called
bl3?

Yes, but this probably doesn't do what you think it does. It will
run chroot /hd /bin/sh, and then _after_ you have exited the chroot
environment, it will run the rc of whatever you are chrooting _from_.

Probably better is to make a script inside /hd. For instance,
/hd/etc/rootsetup:

#!/bin/sh
/etc/rc.sysinit # Change this to the correct script name(s)
/bin/sh

For BL3 it is 'rc'.

# SNIP

Then chmod +x and do: chroot /hd /etc/rootsetup

This will run rc and then /bin/sh, which sets the path specified in rc and then adds what is in profile to later in the path? I will experiment with this.


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?

Because /bin/busybox is no longer a directory in BL3. The
busybox location in now in /bin (and there are some things
in /sbin and /usr/bin and sbin)

/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?

sh is supposed to do that. However, ash may need a special
option to tell it to run profile first.

I think just sh is doing that because startx worked and profile is what put X11R6 on the path.

2.6 is very unstable, due to the Bitkeeper fiasco and various
other issues which slowed down development.

What is a Bitkeeper fiasco?

Linux developers used Bitkeeper to manage the Linux source code
up until the past few months. However, the maker of Bitkeeper
has recently announced that it is discontinuing its free (as
in gratis) version of Bitkeeper on July 1. So, Linux kernel
development is slowing down temporarily, because it is necessary
to switch to a different source code management system. This
takes some time which would otherwise be spent improving Linux.

I did not know that you could release something free and then take it back, or is it just that they are not letting people use the newest version for free?


You may know that odd-numbered Linux minor releases (e.g. 2.5)
are unstable, while even-numbered ones are stable (2.4).
However, 2.7 is not yet ready, so 2.6 is effectively the
current unstable version, while 2.4 is stable and 2.5 is
obsolete.

2.5.something is the first version where they fixed the bug in the kernel that kept cdrecord from working with my CD-ROM drive. We will see if Ubuntu can work with it. I think they may use some other Cd burning program anyway - do you happen to know?

Do you know if we can just snip the wire that replaced the jumper on a board which can take either AT or ATX power supply? A Tyan with 350MHz AMD K6-2 just got left on our doorstep as a kit, in a case with AT power supply, but hardwired to ATX. I can test video cards in it once we get it working. We have no extra ATX power supplies. It has four ISA slots (so I can really mess things up with too many IRQs taken).

Do you know why a modem that we just flashed from x2 to x2+v90, which used to connect at 31200 with port speed 115200, now won't connect at all with that port speed, and with 57600 sometimes connects, but at 28800? Phoebe Micro, so it won't take the USR command to disable X2 (S32=34).
