What I do is to run an fai softupdate via a line in cron upon reboot.

@REBOOT root fai --class=POSTINSTALL softupdate

Kind of nice to do an FAI softupdate after every reboot -- especially the 1st one after the initial install. Over the years, I've moved more and more stuff into the post install softupdate. This has 2 benefits. First, the initial install takes only 5 to 10 minutes. Secondly, I can almost do a normal install from a CD and do the softupdate and get the same results as if I did a fai install in the first place. So essentially what I am suggesting is that you run your script after every reboot, not just the first one. It can be very convenient to have a script that is run after each reboot. Personally, I update that script via an fai softupdate. In other words, the softupdate is updating the next softupdate. That can get tricky. Make a mistake and the softupdates come to a screeching halt. Then you have to figure out some way to copy a repaired script to all your fai machines. I did that once or twice early on but now I haven't messed it up in years.

Hi,

I have a script with some commands that should be executed on first reboot 
after installation only. Now I could put a call to it into rc.local and delete 
it afterwards, but I’m sure I have seen a more elegant solution directly with 
FAI. Could someone point my nose to the right direction?

Thanks in advance,
