Many thanks to all who responded - since there where many, I'll include two. The first I actually used successfuly, the second I included because I liked step 11 :). All answers where great and thanks for everyones time - I even learned some other useful tips

********from Jeff Kennedy*******
Your best bet is to shrink /var and use that space in /. Run 'format' to
find out the block range. You are in luck since /var is on slice 3 and
nothing but swap is in between, makes it easier to deal with. You'll need
to dump / and /var, increase /var's beginning block, move swap up by the
same amount, then increase /'s end block.
I did this not so long ago with /usr, not that bad. Don't forget to
'newfs' the /var and / partitions once you've moved them. You'll have to
boot off cdrom to restore. All in all about a 1 hour process if all goes
well.
Let me know if you have other questions on this.
*******from Rich Kulawiec*********
The most cost-effective and fastest way to do this is:
1. Go get another disk (internal or external.)
2. Drop it in and format it. Partition it so that you have at least
one partition with several hundred Mbytes.
3. Boot in single-user mode.
4. Mount the partition from (2) as /var.new
5. Use ufsdump/ufsrestore (or whatever you like) to copy /var to /var.new.
6. Adjust /etc/vfstab so that /var.new will be mounted on /var the
next time you boot.
7. mv /var /var.old
8. mkdir /var
9. Reboot. Now check to make sure that everything is working properly:
you should be running off of the new /var, which is much larger than
the old one. Once you are satisfied that all is well, then:
10. rm -rf /var.old
You now have some room on your root partition; you also have a much
larger /var, which you will need in order to install patches (as well
as for other purposes).
11. Find the short-sighted person who inflicted this pain on you
and explain to them how many beers they owe you

Hello !
Sorry for a basic question, but I haven't been able to locate the answer in any FAQs.
I have a machine running solaris 2.5.1. Whomever set up the machine allocated a very small amount for /. The partition is now at 100% and I am unable to add a package which I need urgently. I did have two other packages installed, which I removed. This did not seem to make any difference in df -k or df -t. I also removed a core file. Is there anything else I can remove/check for ? What's the best way to increase the size of / ?
Thanks and again appologies if this has been answered before or is too basic !! I will summarize.
regards,
john
