Debian on a system with Compact Flash, without Hard Disk

Don't you think you would have heard about it if this happened easily, considering the number of iPod's that are out there - must be some people who accidentally shut down the power on their iPod [or run out of power or whatever] whilst the device is writing to the flash-device.

I quite agree. i will try to further discuss about it with my colleague who disagrees with you.

is that correct?
I am preparing a prototype for driving cameras and analyzing images. I do not need much stuff to run. Just my threads, a few servers like ssh or ftp and very probably also Eclipse to avoid cross compiling.
Cannot I just install the minimal needed so that probably the OS will not write much on flash and corrupt it?

Thank you

All filesystems really used by Linux except ext2 have journalling.

great!
and you think that it protects fine the flash from sudden power off?
