I have a machine which I have recently upgraded using cvsup, from 4.x
to RELENG_5, as a staging post en route to 7.x. The upgrade went well
until installworld ran out of disk on / and I realised it was only
64BMB. My bad; should have checked before upgrading. With help from
an on-site colleague the installworld was nursed to completion. But
can I get the same machine up to 6.x or 7.x without repartitioning?
Advice please.
Partitions are as follows.
ad0 2439 M
ad0s1 2439 M
ad0s1a 64 M /
ad0s1b 128 M swap
ad0s1e 1024 M /var
ad0s1f 600 M /home
ad0s1g 623 M -
ad1 57259 M
ad1s1 57259 M
ad0s1a 10240 M /usr
It occurs to me that if ad0s1a is insufficient then I could use ad0s1g
as swap, and repurpose ad0s1b as a new /. Is it straightforward to
installworld/mergemaster to somewhere other than / ?
That is very well doable. On boot you can interrupt the boot process by
pressing space an set another location for the kernel.
More information is here.

The rest is just about files.
After you copy everything in ad0s1b (with a fs in it) you can boot from
ad0s1b:/boot/kernel.
I think you can do something like make installkernel DESTDIR=/blabla, but
I'm not sure.
Maybe more easy is booting with a LIVE-cd. Than you can mount everything
needed for installworld in /mnt/tmproot, so you get:
/mnt/tmproot mounted the _new_ / partition (ad0s1b?)
/mnt/tmproot/usr where /usr is mounted (ad0s1a)
/mnt/tmproot/var where /var is mounted (ad0s1e)
Do a chroot /mnt/tmproot and than run installworld and mergemaster as
usual from /usr/src.
Don't forget to make a backup. It is on your own risk. ;-)
