:> 'kern.conf_dir' which the kernel initially sets to nothing.

:ok, i can only suggest that if you replace the sysctl kern.conf_dir
:variable with a shell variable as i did, you can achieve a more
:portable result (this also in light of Jordan's idea of having a
:2.2S CD being made... putting patches for diskless into some
:'xperimnt' directory would be helpful). Other than that, i have no
:objections, and i am very glad you raised the issue since i am
:using diskless machines a lot!
That's what I had originally, but extracting the machine's IP
address is not trivial, and I didn't want to stick:
bootp_ifc=`route -n get default | fgrep interface | awk '{ print $2; }'`
bootp_ipa=`ifconfig $bootp_ifc | fgrep inet | head -1 | awk '{ print $2; }'`
In /etc/rc.conf in roder to synthesize the directory containing
rc.conf.local.
So I have rc.diskless figure it out and sto it in kern.conf_dir, and
rc.conf extracts it from that.
:I haven't seen how you suggest to build&populate the MFS filesystems --
:right now i use a rather crude method of putting all the stuff in a tgz
:archive on the server and expanding it at runtime on the client. I
:haven't solved the problem with passwords (i.e. i just copy the files
:from the server. -- this is clearly a security hole, perhaps YP-based
:solutions would be much better).

There isn't much to build. Most of the MFS filesystems start out
empty.

/var/run - starts out empty
/var/db - starts out empty
/var/tmp - starts out empty
/var/spool - simple skeleton directory structure
/dev - mount server:/ to a temporary place and use cpio to populate
/home - populate from template ( up to the user, I include a sample )
If I wanted to make a full system, I suppose I would make /var an MFS
filesystem too and use the system mtree to create it's directory structure.
But most diskless workstations do not need to run cron :-)
