There has been some discussion lately about possibly changing the defaults.
If you become faced with having to reinstall jot down your current partition
sizes and adjust manually making / larger.
Since it is full, if you intend to try and recover it will entail deleting
something. This could get tricky, especially if the new 'kernel' space is
what filled up. This would presuppose that the kernel.old area was already
written out successfully. If the machine will not boot successfully with the
new kernel it is imperative that kernel.old still be healthy in order to
recover. However, if the new kernel does actually boot, with the result
being that some modules are missing you may be able to delete the kernel.old
in order to buy space. Messing around with this can potentially be
problematic, for obvious reasons. A strong 'YMMV' is indicated here.
If you can get past that, you may be able to mitigate the / being too small.
Place STRIP= -s into /etc/make.conf and WITHOUT_PROFILE= true into
/etc/src.conf. The con of this is that you lose some debugging ability. The
pro is new kernels will now fit. I have two servers set up this way at home,
and one uses 91MB while the other uses 93MB of space. The 91MB one only has
a / of 200MB total, and is nearly half empty. Allows for rebuilding and
installing a new kernel without running out of space.
