: just got to work with a device from Ipsilon (now part of Nokia).
: its a CheckPoint FireWall-1 running on top of FreeBSD :)
: The root filesystem is mounted read-only.

: rather than addressing make.conf vs make.conf.local,
: how about taking this issue on...getting us a read-only
: root filesystem. it'll take moving all the changing and

: pointing to them...you'll take some heat but the results

I'm currently booting a diskless workstation via NFS/BOOTP. It mounts
my main server's / and /usr partitions read-only. Works great! The
diskless workstation is even running an almost-complete set of services.
The only real problem I had was that I had to hook my rc.diskless boot
script nearer to the beginning of /etc/rc so it wouldn't try to mount
non-existant disks and such, and the 'xdm' program tries to create
two log files in /usr/X11R6/lib/X11/xdm somewhere which I had to
redirect to /var/run/ using softlinks.
After that it was just a matter of creating MFS filesystems for /var,
/var/run, /var/db, /var/tmp, /dev (tty ownership), and /home.

I'm using persistent MFS mounts on two of the partitions... I've got a
number of MFS-related patches which I haven't commited yet that allows
for persistent backing store (and, in fact, you can even fsck the
backing store file prior to MFS-mounting it! Hoa!), and one that deals
with MFS-related paging issues. But even without the hacks it can be
made to work quite well.
