PXE + sysinstall(8) install.cfg: DHCP Attribute to map install config/policy to system MAC?
All:
The install.cfg mechanism is pretty wicked.
Unfortunately, there doesn't seem to be a really efficient way
to provide new clients (or class of clients) an install.cfg
without rebuilding an MFSROOT image.
At least with pxeboot(8), in TFTP-only-mode, using
dhcpd.conf(5) client{} entries, there isn't a way
to differentiate policies.
It's just going to go looking for /boot/loader.rc
and /boot/loader.conf from wherever DHCP told PXE
to fetch pxeboot(8) from.
From there, you need to custom compile a 5 meg
mfsroot image for each [class of] client.
With an NFS stage-2 boot, I suppose you could set:
option root-path /export/${client}Root etc.,
but then your 5 meg mfsroot is just extracted
1-per-client.
Still seems a bit ugly. It seems like we could teach
sysinstall(8) to fetch install.cfg by some standard
mechanism.
Possibly a TFTP or NFS URL passed from the DHCP server
- boot loader - kernel sysctl - sysinstall(8).
For example, the Sun SPARC4s would TFTP fetch their
stage 1 boot loader via TFTP with a filename req
of their MAC address in HEX format, so one could
just put symlinks in place.
Thoughts or other ideas?

PS: our in-tree tftpd(8) is an unending source of sorrow and misery and
clinical despair. ports/net/freebsd-tftp is a lifesaver (it actually
has debugging)

You can configure sysinstall in your install.cfg to execute shell commands, including any fetch-like command. Some scripting should be possible to do what you require. I wrote about it here: http://www.locolomo.org/howto/pxeboot/automatic-installation.html However, I never really went on and tested this, let me know if this works.

Sysinstall with install.cfg
Hello, I've been tasked with building a modified FreeBSD release, which among other things should have a scripted sysinstall. However when I try to use a basic one I get an error saying something like: No such device /dev/da0s1b, but in the debug output I see that it was created. The install.cfg I'm using is: debug=yes # Which installation device to use mediaSetCDROM # Select which distributions we want. #dists= #distSetCustom distSetDeveloper # Now set the parameters for the partition editor on da0. disk=da0 partition=all bootManager=none diskPartitionEditor diskPartitionWrite da0s1-1=ufs 62914569 / da0s1-2=swap 16777216 none da0s1-4=ufs 0 /usr diskLabelEditor installCommit What am I missing?
