Fwd: Adding Macs with FAI

[Juri Grabowski]

Hello,

I would try this with ipxe as iso or usb drive or as new entry in your
bootloader + network boot with fai.
You can embed ipxe config to image or make use of your dhcp.
# just a part of dhcpd.conf from isc-dhcp-server package:
   if exists user-class and option user-class = "iPXE" {
	set hwmac = concat (
	suffix (concat ("0", binary-to-ascii (16, 8, "", substring(hardware,1,1))),2), ":",
	suffix (concat ("0", binary-to-ascii (16, 8, "", substring(hardware,2,1))),2), ":",
	suffix (concat ("0", binary-to-ascii (16, 8, "", substring(hardware,3,1))),2), ":",
	suffix (concat ("0", binary-to-ascii (16, 8, "", substring(hardware,4,1))),2), ":",
	suffix (concat ("0", binary-to-ascii (16, 8, "", substring(hardware,5,1))),2), ":",
	suffix (concat ("0", binary-to-ascii (16, 8, "", substring(hardware,6,1))),2)
	);

      filename = concat( "http://$FQDN/", hwmac );
   }

You need webserver on your fai-server.
In you http DocumentRoot you need symlinks like that:
ln -s /srv/tftp/fai/pxelinux.cfg/01-52-54-00-00-00-00 52:54:00:00:00:00
ln -s /srv/fai/stretch-nfsroot/boot/initrd.img-4.9.0-3-amd64 /var/www/html/stretch-initrd
ln -s /srv/fai/stretch-nfsroot/boot/vmlinuz-4.9.0-3-amd64 /var/www/html/stretch-kernel

And your fai-config template should looks like that:
#!ipxe
#dhcp
kernel http://$FQDN/stretch-kernel boot=live components root=live:http://$FQDN/stretch-squashfs.img noswap live aufs kernel.sysrq=1 sysrq_always_enabled log_buf_len=1M quickreboot consoleblank=0 keep_bootcon initrd=stretch-initrd rootwait=120 rd.live.image rd.neednet rd.luks=0 rd.lvm=0 rd.md=0 rd.dm=0 rd.driver.pre=loop rd.noverifyssl rd.skipfsck rd.live.overlay.check rd.live.overlay.reset rd.live.ram FAI_FLAGS=verbose,sshd,initial,createvt FAI_ACTION=install FAI_CONFIG_SRC=$YOUR_FAI_CONFIG_SRC LOGUSER=fai
initrd http://$FQDN/stretch-initrd
boot


Your Squashfs image you can build with: fai-cd -Mef -d "" stretch-squashfs.img
after "fai-chboot -c $TEMPLATE $HOST" you should remove the first line
with "sed 1d /srv/tftp/fai/pxelinux.cfg/$HOST" or use patched version of fai-chboot
to avoid "# template generated by fai-chboot for host" on first line.

After this manipulations you can boot your macbook with ipxe and start
the installation over http.
