Can you try miniroot installation of 5.0.1? (it doesn't have wscons)

upgrading from old 2.4.x to 5.0.x


I've got a system (Sparc 20) running a quite old version of NetBSD (2.4) 
and I noticed that NetBSD is now up to 5.0.x.

For anyone who's upgraded from old to new releases, what is the best way 
to go about it?

Craig.

It probably depends on what your machine does, what applications are
installed and in use, and whether you want to upgrade them up too or not.

Though I haven't done it on a NetBSD/sparc machine, nor with an upgrade
from such an older release, you might want to try the "sysinst" upgrade
procedure by booting from new install media (eg. a 5.0 sparc cd-rom).

It might be easier though to build/acquire the install sets and a new
kernel, install and boot the new kernel into single-user mode, unpack
the non-"etc" set(s) and then run etcupdate with the new "etc" set(s)
and merge/install config file updates as desired.

roughly like this:

    mv /netbsd /netbsd.old
    gzcat /RELEASE/sparc/binary/kernel/netbsd-GENERIC.gz > /netbsd

    reboot (into single user mode)

    cd /

Well, there's two aspects to that, the base system, and pkgsrc.

The base system is the easier part:

(0) If your ss20 is an SMP system, rip out all cpus but one, or stick 
with netbsd-4, since netbsd-5 smp does not work on sparc.

(1) Copy the netbsd-[45] distribution to your harddisk, preferably a 
daily snapshot of the netbsd-[45] stable branch.

(2) Install a kernel as /netbsd[45], and boot that. GENERIC kernels 
have all the compat* options and so should work fine with your 
netbsd-2 userland. If it works; great, if not, you need to update the 
boot blocks first.

(2a) For updating the boot blocks, unless you have a second machine 
around, print out the installboot(8) man page and the install 
document first. Depending on your hardware, either boot from an 
install cd, or dd(1) the install kernel to the swap partition, and 
boot from that. In sysinst, drop to the shell prompt, mount the root 
partition, copy boot, and run the proper incantation of 
/usr/mdec/installboot.

On netbsd-5 can you just use GENERIC rather than GENERIC.MP and run
reliably on one proc on an SMP box?

Actually I made a little error - the system is running an even older 1.5.2 
release. 8-) It's single-CPU though - running 1 x SS71 processor.

Disk is a 1.6" 146 GB drive which gets quite hot so that'll go soon.

Craig.

Heh, I ran 1.5 & 1.6 on sparc10 & sparc20s for *ages*. Nice boxes,
pity I didn't have the space/power to keep them :( :(

Was that a.out still, on sparc, or already elf? In the latter case, 
you'd have to read the UPDATING and INSTALL information from the 1.6 
release, I guess.

Good, at least here.  ;)

The ss20 will take any SCA2 scsi disk, so replacing it shouldn't be a problem.

One thing that may hold a nasty surprise: Unpack etc.tgz before 
anything else, and copy the "pam.d" directory to your /etc. Kernels >

When I tried on my ss20 (2x SM71, thanks to Martin) a few months ago, 
the UMP kernel got a bit further, but failed eventually. While there 
has been progress on -current, I am not sure any of the changes have 
been pulled up.

re: upgrading from old 2.4.x to 5.0.x


plain GENERIC should work fine if the system has multiple CPUs.
if that fails, please file a PR or at least show some more info?

anyone want to help look at the SMP problem?
