Another mini-distribution (White Dwarf Linux) is available here : 
http://www.blast.com/index.php?id=35 

To avoid writing to your compact flash, you can mount the root in
read-only (option to pass to lilo/grub)
And have a ram-disk that will be mounted to /var where you have some
files that can be written (not sure that it is enough...)

Bye.

Another one here, that seems very interesting :

http://www.rts.uni-hannover.de/lire/

" LiRE V0.6.1 released / 18.08.2006
This release contains the Linux Kernel 2.6.17.8, Xenomai 2.2.0, RTnet
0.9.4, RACK 0.3.0, BusyBox 1.2.1, bugfixes and some new features like
QEMU Image Support. "


Bye.

Thanks for the AD ;). I always hesitate to announce this to loudly as it
is still in a rough state /wrt generic usability. BUT -- it does what it
should do in a very straight way: install a mini Linux/Xenomai system
for x86 + some arbitrary tools (for us of course not arbitrary) on a
flash card. In fact, most of my tests run on LiRE, either netbooted on
some PC that happen to be in reach (Etherboot is your friend) or in
qemu. And of course all our robots run on LiRE.

We are now working on the next generation of LiRE which will likely be
based on some smarter third-party build system, specifically to ease the
pain of adding and maintaining more and more packages.

If there is interest here in joining our effort, let us know. There is
no real community around LiRE yet, just a few users at another
university institute in Hannover and at the R&D department of an
automotive manufacturer (and those guys are typically _very_ silent) -
that's at least what we are aware of. But I could imagine that providing
such a cross-compilable (todo...) distro with Xenomai included may be
helpful for quite some users.
