I have been using grml for a couple of days and I am very happy with it so far. The reason I started to use grml was that I discovered that the grml kernel was configured with the PREEMPT option. This makes it suitable for audio applications and even if the preempt characteristics you get with an RT-kernel is "better" the PREEMPT option of the vanilla kernel seems to be "good enough". With grml I get both a system that is easy to configure to me needs, boots off a USB stick and has a PREEMPT kernel :).
I have looked at most distros out there and it is very rare to find ones that comes with a PREEMPT kernel as standard, so this makes me wonder why the grml team choosed to provide PREEMPT as a standard configuration. Anyone that knows this and wants to share why grml is using a PREEMPT kernel? Going forward, will the PREEMPT configuration option remain as standard in grml or might that just suddenly change?
Kind Regards

Well, we are using preempt because it's "the right way to go" and worked reasonable well (well, we had some issues regarding the speakup kernel modules but the problems seem to have been fixed in recent versions of speakup). :)
Going forward, will the PREEMPT configuration option remain as standard in grml or might that just suddenly change?
As long as we don't experience any serious bugs or reasons to change this behaviour preempt will stay the default in grml's kernel, yes.

holy crap, I can't believe I missed this!!!
what version(s) of grml support the PREEMPT option? (i.e., stable or development)
this is really great news. ;)

Hm, all grml versions? ;)
