Hmm, my minimal rootfs is (so far) 7 Mb, (as reported by du -s). Or, is this 4Mb you cite compressed? I wonder because my libc.so is over 5 Mb. (which I got from DENX eldk-1.0) Instead of ldd, I used "objdump -x $library | grep NEEDED" which has the advantage that you can (er, that I know how to :-) run it in a cross environment, so I don't have to fire up the powerpc just to run ldd on a bunch of binaries. (maybe there's a way to cross run ldd? ) Using that, I wrote a script (just today, as a matter of fact) to scan all the executables and their libraries (and links to libs) iteratively until it produced a minimal set, then deletes whatever isn't on the list, which got me down to 7Mb with busybox and tinylogin as my only apps. (It occurs to me now that apps using dlopen() could be a problem, but those are relatively rare.) Any hints or links to into on crunching down the individual libraries would be helpful. BTW, nice book. -- steve ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
