Welcome!  Gotta love these 20" screens!

Ah, reduce, reuse, recycle.  Good stuff.

Hah!  I've just worked on that very problem.

It seems the kernel gets written to /boot/vmlinuz-2.2.19-sun4cdm
and a link gets created (see below for how) to link
/boot/vmlinuz to /boot/vmlinuz-2.2.19.  So the link from vmlinuz
points nowhere.

I fixed this by editing /etc/silo.conf to say:


(it used to say image=1/vmlinuz-2.2.19, or was it just image=1/vmlinuz?
no matter)

You should probably edit it to say 2/vmlinuz-2.2.19-sun4cdm -substitute
your kernel version - I was installing potato stable R 4.

The 1/ and 2/ are which partition the image is on.  In my case boot
is on the first partition so I write 1/vmlinuz-2.2.19-sun4cdm
Your boot is on your second partition so you write 2/vmlinuz-2.2.19-sun4cdm.
Leave off the /boot part of the path, because that's _not_ on your
second partition.  Your vmlinuz image really is at the top of your
second partition.

Note that I put /boot on the first partition because I wanted to make
absolutely sure that the image would be at the beginning of the disk.
But your arrangement puts the image close enough to the beginning of
the disk so you don't need to re-arrange it now that it's done.

No special partition for /tmp, so it will share /, and you have only 50MB for /
Well I've never run a dedicated server, but I'm wondering if you haven't
skimped a bit on /tmp space.  Servers may (or may not, depending on how
you've configured them) use a fair chunk of /tmp space.

Also you can configure some servers to run as their own user, so they might
need space in /home.  Eg, amanda (a tape backup software) might be installed/
configured to run as user amanda.  This is handy to keep servers from
tromping on each others files, either inadvertently or as a way to
limit the damage that a cracker can do once they "own" a server.
Of course you can always set their accounts in /usr... not sure
what the FSH has to say about this topic.

Maybe someone more experienced with servers/security can comment.

I think there's a wee bug in the install program, you didn't do anything
wrong.  This bug only seems to show up when you have a separate boot partition,
as you noticed.

I don't have a floppy drive in my SS20, sorry can't help you here.

ln -s old new
