[comp.os.minix] Upgrading 1.1 to 1.2: is there anything I need to know?

allbery@ncoast.ORG (Brandon S. Allbery) (03/05/89)

I just grabbed the 1.1-1.2 diffs from bugs.nosc.mil in an attempt to get
my Minix up to the current level.  I haven't yet looked at the tar file to
see if there's a readme in it, as I prefer to minimize the size of files
(i.e. keep them tar'ed and/or compressed) on the intermediate system (uunet)
where I can FTP from; so be gentle with me if it's described there.

Anyway, I'm running 1.1 with a few minor hacks (mainly, I added /etc/mnttab
to mount, umount, and df so I didn't have to try to remember what was mounted
and so I wouldn't have to type as much to see all of disk space on up to 4
devices (/dev/ram, /dev/hd2, /dev/hd3, /dev/fd0); and the 1.2 mpx88.s and
xt_wini.c so my hard drive would work).  I do *not* have most of the stuff
that went by comp.os.minix before the 1.2 update -- my original setup is
long gone, I built the current one solely from my 1.1 disks and the above-
mentioned patches.  (Oh -- one other hack:  my ramdrive is only 80K, with
most of the stuff not necessary to boot now in /usr/bin or /usr/lib.  I can
build a minix with a larger ramdisk, but won't unless minix 1.2 somehow
installs itself onto the currently-running system.  I'll know when I see it.)

The $64,000 question:  is this sufficient?  Should I start with an unpatched
1.1?  Do I need to grab some of the 1.1 enhancements from bugs.nosc.mil?  The
readme file outside the tarchive was not particularly helpful with this
question; I hope that a better readme is inside the tarchive, but I'm asking
here just in case.

While I'm thinking about it:  I will upgrade to 1.3 as soon as I've got 1.2
running stably.  Will this install on top of the bugs.nosc.mil 1.2 update,
or will I need more for that, too?

And one more question:  the binary "afio" recently posted can't open the
console *or* /dev/tty (I tried linking /dev/console to /dev/tty to see if
it was a bug in /dev/tty).  I didn't notice any bugs off-hand in the tty
code of 1.1, although that is such a mess that I couldn't really hope to.
*Is* there a bug?  If so, is it fixed in 1.2?  1.3?  It'd be real nice if I
could do a backup of my Minix partition instead of losing it like I did my
original Minix partition....

Thanks in advance,
++Brandon
