At the risk of appearing totally foolish, I've been mounting /usr/src (useful for cvs update), /usr/obj (useful during "make world") and /news (expire is happy!) and the CVS tree (useful for CTM) async for more than a year. Had a few crashes, still have to lost anything. Even during the earlier time of async support by John, I didn't got any unsolvable problem with it. /dev/sd0a on / (local) /dev/sd0d on /usr (local) /dev/sd0h on /usr/local (local) /dev/sd12e on /var (local) /dev/sd0f on /users (local) /dev/sd12f on /news (asynchronous, local, nosuid) Usenet (small part.) /dev/sd0g on /src (asynchronous, local) /usr/src /dev/sd12g on /spare (asynchronous, local) CVS tree /dev/sd0e on /work (asynchronous, local) mostly build of prgs /dev/sd11a on /x (local, nosuid) FTP server /dev/sd12h on /y (asynchronous, local) /usr/obj procfs on /proc (local) Sound scary I know, but works perfectly well. Result ? 4h50mn for "make world" on 486DX4/100, 32 MB, 2x SCSI controllers (sd0 on bt0 and sd11 and sd12 on ahb0). Yeah, I enjoy risk :-) -- Ollivier ROBERT -=- The daemon is FREE! -=- roberto@keltia.freenix.fr FreeBSD keltia.freenix.fr 2.2-CURRENT #12: Sun Jun 30 14:10:07 MET DST 1996
