Here are my two stock post-install scripts that I drop into the
/var/lib/systemimager/scripts/post-install subdirectory. One updates the
e1000 driver options (it can reduce latency by up to 70% on HPC
systems), and the other adds the /dev/shm entry to
modules/modprobe.conf.

For me, this works well enough for now.
