Is it possible to tell installkernel to put the symbol files elsewhere? IMO somewhere in /usr would be good - you don't need them to boot (or crashdump, etc) and they increase the size of the kernel by a factor of 5(!), eg.. [cain 14:07] /tmp >du -sh kernel 258M kernel [cain 14:07] /tmp >rm -f kernel/*.symbols [cain 14:07] /tmp >du -sh kernel 50M kernel One downside is that you need to keep them in sync which is a bit of a drag, however I think most people use installworld for upgrades/builds so it would generally not be an issue. I think this is the main reason / has had to grow - the actual kernel is relatively small so even a 256Mb / could hold several, but with the symbol files it is not possible. I don't have patches to do this though :) -- Daniel O'Connor software and network engineer for Genesis Software - http://www.gsoft.com.au "The nice thing about standards is that there are so many of them to choose from." -- Andrew Tanenbaum GPG Fingerprint - 5596 B766 97C0 0E94 4347 295E E593 DC20 7B3F CE8C

I wondered the same.

I think a very simple solution would be to install the symbol
files elsewhere (probably configurable via make.conf), and
install symlinks in the kernel directory. If you do this,
tools using the symbol files won't have to be changed.
This would probably be a fairly trivial change to the install-
kernel target, I guess. I don't have patches, though.
Best regards
