All
I wanted to share with you my method for network installs of FreeBSD
9.1-RCn . This does not use PC-BSD just stock FreeBSD. This should
work on 9.0-RELEASE is known to work on 9.1-RC's and BETA.
I decided to use pc-sysinstall in place of bsdinstall as pc-sysinstall
supported using a config file that could be passed to the installer
much like the old sysinstall way of doing things.
Jumpstart host:
--------------------------
Exported filesystems: /export/
Useful paths on /export, /export/install/freebsd/9.1/{i386,amd64}
this is the contents of the install media rsync'd to a local filesystem
TFTP configured to server from /tftpboot which is a symlink to
/export/install/freebsd/9.1/{i386,amd64}
DHCPD configured as follows
subnet 10.1.5.0 netmask 255.255.255.0 {
authoritative;
option netbios-name-servers 10.1.5.252;
option routers 10.1.5.1;
option subnet-mask 255.255.255.0;
option broadcast-address 10.1.5.255;
option domain-name "ops.com";
option domain-name-servers 8.8.8.8, 10.1.5.101;
next-server 10.1.5.28;
option root-path "/tftpboot";
filename "/pxeboot";
default-lease-time 21600;
max-lease-time 43200;
}
Changes to make the install media boot the way I want it.
--------------------------------------
1. I copied boot/pxeboot to /export/install/freebsd/9.1/{i386,amd64}
thats a work symantic not required
2. I created a conf directory to store my pc-sysinatll configs
3. I added the following bits to rc.conf to make the nfs root happy
sendmail_enable="NONE"
hostid_enable="NO"
update_motd="NO"
hostid_enable="NO"
varmfs="YES"
hostname="jumpstart00.ops.com"
4. I modified the fstab file as follows
#/dev/iso9660/FREEBSD_INSTALL / cd9660 ro 0 0
none /tmp tmpfs rw 0 0
5 I changed my rc.conf to start a simple shell script and not the
bsdinstall bits
export TERM=vt220
echo "o PC-SYSINSTALL "
exec /conf/picker.sh
6. Here is /conf/picker.sh
#!/bin/sh
: ${DIALOG_OK=0}
: ${DIALOG_CANCEL=1}
: ${DIALOG_HELP=2}
: ${DIALOG_EXTRA=3}
: ${DIALOG_ITEM_HELP=4}
: ${DIALOG_ESC=255}
dialog --backtitle "FreeBSD Jumpstart" --title "Welcome" --no-label
"Shell" --yes-label "Install" --yesno "Welcome to FreeBSD! Woul
d you like to begin an installation or use the live filesystem?" 0 0
case $? in
$DIALOG_OK) # Install
exec /conf/disk.sh
;;
$DIALOG_CANCEL) # Live CD
;;
esac
7. Here is /conf/disk.sh
#!/bin/sh
: ${DIALOG_OK=0}
: ${DIALOG_CANCEL=1}
: ${DIALOG_HELP=2}
: ${DIALOG_EXTRA=3}
: ${DIALOG_ITEM_HELP=4}
: ${DIALOG_ESC=255}
dialog --backtitle "FreeBSD Jumpstart" --title "Select disk type"
--no-label "SCSI/SAS da0" --yes-label "IDE/SATA ada0" --yesno "Se
lect Your servers root disk type" 0 0
case $? in
$DIALOG_OK) # Install IDE/SATA
exec /usr/sbin/pc-sysinstall -c /conf/ada-install.cfg
;;
$DIALOG_CANCEL) # Install SCSI/SAS
exec /usr/sbin/pc-sysinstall -c /conf/da-install.cfg
;;
esac
exit 255
The install config
------------------------
I created /conf/ada-install.cfg and /conf/da-install.cfg the only
difference here is the name of the disk as that is not auto
discovered.
Here is ada-install.cfg
# User Generated pc-sysinstall configuration
installInteractive=no

Notes
1. The package install its some hoop jumping but it works. I hope that
Kriss More with add a macro to handle this in the future. I would like
it use to PKG_PATH to make this simpler.
2. The installed FreeBSD originally came from the fbsd-release.txz on
the pc-bsd mirrors however you can provide you own . Work is being
done to make this macro use the FreeBSD tar
balls provided on the install media . That may make it into
9.1-RELEASE but I doubt it.
Thanks to Kriss More for all his help.
