People with tons of swap can safely yawn & skip this posting :-) Those tight on swap space may like to read on... You'll recall /usr/ports/net/cvsup used to be difficult to build as it gobles swap (used to abort for me, with 16M RAM & 2 * 32M swap partitions & X-11 & EXMH & ghostview & nfs etc running ... Well I now run a kernel including pseudo-device vn & created a 40M file to use spare space on my mounted dos file system, then used it with vnconfig /dev/vn0b /dos1/tmp/swap swapon /dev/vn0b & cvsup make ran fine, just took a while, (while I was out, so don't know what high point of swap usage was achieved). I noticed it was a new cvsup version (13.4) I'd previously tried making some earlier version. My kernel & binaries are from CVS src Sep-1 (with share/mk Sep-15) After I had Device 1K-blocks Used Avail Capacity Type /dev/sd0s2b 32768 7992 24712 24% Interleaved /dev/sd2s2b 32768 7680 25024 23% Interleaved /dev/?? 39578 3284 36230 8% Interleaved Only problem is I suspect running a swap on a DOS FS may not be a bright idea for long term performance stability etc, so I wwant to reboot to drop the /dev/vn0b, but I've got to wait, cos this box is nfs serving src for another box that's running a _very_ slow make world (& has been for 2 days or so (slow box, I have to check into that)), ... hence I can't give a report on `current' vn etc, but at least cvsup make swap requirement seems to be surmountable, without permanently reconfiging disc allocations :-) Julian --- Julian H.
