Assuming they're next to each other on disk, I'd probably remove sd1m and sd1n and create and newfs a single new partition in the space. 6GB is probably enough for /usr for a while. (Or if sd1o is also adjacent, there's another possible 4G). Edit fstab to put /usr there - either comment out the existing /usr or put it on /mnt or somewhere. Basic knowledge of ed(1) is helpful here. Reboot onto 7.6 bsd.rd and do an upgrade install to 7.6 again to install missing files from all sets. Even if not adjacent, there's still a choice of ~4GB partitiona to requisition, but 6GB gives a much more acceptable headroom. (You can probably fix it in the existing 2GB by removing old libraries and doing an upgrade install, but that's very much a short-term fix). I doubt you have anything that's not part of base in /usr but if you do, recover it from the old partition. > Is there a way to get access remotely?
