It's not too hard > to have a minimal system entirely on the RAM disk If I want to use a filesystem containing read-only files (executables and data files) which is 2 MB for example, I would require either: *  2MB  conventional filesystem (e2fs) mounted read-only, using no dedicated RAM (other than caching/buffering), but using 2MB of the flash disk (50% in my case). * compressed RAM disk mounted as an initrd, using 2MB RAM (out of the 8MB DRAM I have), but only 1MB flash (25% of the DOC2000-4MB I use, assuming 50% compression ratio). * CRAMFS based partition using 1MB flash and no RAM. Ofcourse, the bigger the partition needs to be, the higher the gains. I'd rather have the 3rd option. Also, where do I find a *complete* list of 2.2 -> 2.3 kernel changes? the only list I found was: http://www.atnf.csiro.au/~rgooch/linux/docs/porting-to-2.3.html and it is certainly lacking. > Stuart Lynne __O > Udi To unsubscribe, send "unsubscribe mtd" to majordomo@infradead.org
