can do but how do I regenerate my autoinstall script? do I redo the
si_getimage? I notice there is also something called
si_mkautoinstallscript on the server. sounds promising but it is not
installed on the client. do i copy this over to the client and use it?
Yes you run si_mkautoinstallscript to regenerate the script (make sure
you make a backup copy before you run it).
The script is executed on the image server, which should contain a copy
of your golden image.
Hi, Bernard.
I changed <the image>/etc/systemimager/autoinstallscript.conf per your
suggestion and ran si_mkautoinstallscript. it generated a new
/var/lib/systemimager/scripts/<the image>.master
this is enclosed. note the order is still the same, i.e. wrong and will
result in an image that mounts root on top of /boot.

#
# Q1) Why did they get started in the first place?
# A1) So we can pull a local.cfg file off a root mounted software RAID system.
# They may not be started on your system -- they would only be started if
# you did the stuff in Q3 below.
#
# Q2) Why didn't my local.cfg on my root mounted software RAID work for me
# with the standard kernel flavour?
# A2) The standard kernel flavour uses modules for the software RAID drivers --
# therefore, software RAID is not available at the point in the boot process
# where BOEL needs to read the local.cfg file. They are only pulled over
# when this script is run, which is, of course, only runnable if it was
# pulled over the network using the settings that you would have wanted it
# to get from the local.cfg file, which it couldn't. Right?
#
# Q3) Whatever. So how do I make it work with a local.cfg file on my root
# mounted software RAID?
# A3) Compile an autoinstall kernel with software RAID, and any other drivers
# you might need built in (filesystem, SCSI drivers, etc.).
