What would "abort" mean? Leave the PXE boot file in place, and just
sit there and wait? Shut down?
A couple of years I had to "reboot" inside a hook when it detected
the wrong RAID configuration (after fixing that, of course) - to get
the hw detection read the right disk names for the install. I can't
see a reason why a shutdown wouldn't work as well - you'd lose the
install log though. Of course you may make the hook run into a loop
of beeps suggesting to ssh into the machine, and check the last lines
of fai.log ... depends on your environment (beeps are hardly audible
if there are 100s of other machine humming next to this one).

Doesn't extrbase do such a check itself, and throw an error code
which can be seen on faimond's output?
