The current revision of conf.c attempts to make life easier for sites with local disk partitions. Adding the keyword "LOCALDISKPART" to the MAKESYS file causes inclusion of "../conf/dkpart.c" (with your local partitions) and "../conf/dkauto.c" (with dktype-to-dkpart mappings) when you compile conf.c. These files are not clobbered by PTFs. If you are in the midst of an upgrade process, of course, you cannot easily put your /usr on a nonstandard partition. If you *really* want to avoid re-copying /usr to its final resting place, you can use a virtual disk to define the /usr paritition, then use a modified load_usr script that knows about vdisks. Of course, you could use vdisks everywhere anyway, except for swapping. (This is probably obvious to anyone who likes local partitions. Me, I'm one of those crazies who still prefers disk partitions no more than 150 MB each, so that any partition can be backed up to a single 6250 bpi 9-track tape.) A comment on the original swapping question: OSx 4.4 and earlier uses the BSD VM system, which I seem to remember, was intended to be run with a RAM-to-swap ratio of 1:4 on VAX 750's with 512KB of main memory. OSx 5.0 uses SVr3 VM, which no longer requires backing swap for every process space in the system. In the absurd case, someone with light system usage and 256MB of main memory will never touch even the 30MB default swap partition. One thinks, however, that someone with that much money would probably spend it on something more interesting than excess RAM. -- ''!!!0289 dimaryP a fo edisni deppart m'I !pleH`` ``oNhwre eenraa sab dsab iegnt arppdei n aAV X117/05!!''
