I've used -o to delete old revisions and have not had a problem with it,
but it is true that it could create issues if you wish to create diffs
against old revisions or re-create old revisions.

I wouldn't expect the growing number of reivisons to create a real issue,
but if you insist and wish to be 100% safe, start with new revisions or
write a script that re-creates a range of versions and commits them under
a new name.  eg:
	for 1 2 3 in ver; do
	  cvs -d ./CVS co -p $ver group/config/host > group/config/newhost
	  cvs commit -m 'updates' group/config/newhost
	done

again, I recommend that you just leave it alone or re-start with a clean
slate.
