I'm sharing a swap partition on linux and win95...when I boot linux I erase the dos files, dd it, and mkswap it (putting back the old image on shutdown). I was under the impression in freebsd you can swap on arbitrary partitions (so I want to use the same strategy). I'm going to swap on OS/2 on the same parititon (its 35 MB). I think NT insists on an NTFS partion to swap.. (??) I strongly encourage making small swap parititons (I'm putting it in extended partitions) then swap files...then if something breaks, its no big deal... What I would like is not to insist on swap when I install (on machines with >16 Mbyte of ram, its reasonable not to have to make a swap parititon). -- marty leisner@sdsp.mc.xerox.com Member of the League for Programming Freedom
