I'm re-sending this because I'm still getting a lot of responses to my
original posting. (I forgot to add anything after "SUMMARY:" in my
original summary -- which is probably when the confusion comes from.)

(I keep forgetting to tell you all that I'm installing Solaris 2.5.)
It turned out that I must have missed some error message somewhere. When
I checked what format saw in the permission table, it saw my old
partitions.
To *really* modify the partition table, I had to boot from the
installation CD and run format from there. After I did that (Shrinking
the root fs to make room for the larger swap space), my machine wouldn't
boot properly. That surprised me because I assumed that it would use the
space at the beginning of the partition first -- that the back-end of the
partition would be free.
Anyway, unless there is a shrinkfs utility somewhere (to shrink my root
partition), then I'm outa luck.
(The reason I didn't want to use swap: I manage 30+ systems here. It
makes thing much simpler if they are all set up in a similar manner.
Having 2-3 systems with a strange vfstab file would really confuse
things.)
Here are some things that people suggested:
1. Create a file and use "swap -a" or "swapon -a" to make it a
second swap space.
# cd /home/swap2 <- cd to a bigger filesystem
# /usr/etc/mkfile 50M swapfile <- makes a 50 Mbyte file or more
# emacs /etc/fstab
/home/swap2/swapfile swap swap rw 0 0 <- add this line to fstab
# swapon -a
2. Back up my other partitions, change the partition sizes, and
then restore the other partitions. (Might have to re-write the
bootblk.)
