first, if there is a better forum in which to launch this, please advise. I would expect your typical ISP environment would run into cases where a single server was NFS serving, multiple OS's as well as multiple architectures. And where itself my need to NFS mount foreign filesystems or loopback on itself. I was setting up such a server which has the following layout and hit upon a nasty snag in the default /etc/rc.* series of scripts. sd0d /export/1 has FreeBSD and OpenBSD userland (./FreeBSD, ./OpenBSD/i386, ./OpenBSD/sparc, ./openBSD/alpha) sd0e /export/2 has Free and OpenBSD's src and ports trees (./FreeBSD/src, ./FreeBSD/ports etc.) sd1d /export/3 has common home directories and such so that my family of client machines mount /usr, /usr/src, /usr/ports and whatnot in a transparent fashion, I don't see how I can get away without loopback nfs mounting the latter 2 (on the server) if I want all machines to be laid out the same way. On the server I can cheat and symlink /export/1/uname to /usr. Though that is not ideal. Turns out though that the rc.network script doesn't get around to invoking nfsd till it's almost done. Worse, /etc/rc didn't get around to initting the network and thereby offering even the opportunity to NFS mount /usr, /var or any other important partition till way late in the game. Has no one run across this of late? I spent a bit of time shuffling the rc scripts around and rewriting a fair chunk of it so that 1) scans /etc/exports for file systems nfsd is going to want 2) mounts them right after /(root) goes RW 3) starts portmap and the other needed nfsd programs (note, portmap has be recompiled as static and moved to /sbin. I guess this one slipped between the cracks) 4) explicitly calls mount on /usr and /var 5) mounts everything else via -a. 6) continues with rest of boot. I also turned up a bunch of logic errors, dependencies, and bad assumptions that are either not enforced or lost. (see various blurbs in rc.conf about running certain daemons only with others or when some other condition is met) If there is interest I can provide diffs. BTW, who do I bounce this off of for further critique and maybe inclusion into the distribution tree?
