Writeable file mappings are just not supported by jffs2, and cause mmap() to return an error. glibc likes to do it when building the locale-archive, and I vaguely remember I had a workaround for this in our fork of the glibc rpm. -- // Bernie Innocenti - http://www.codewiz.org/ \X/ Sugar Labs - http://www.sugarlabs.org/ ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

As far as I know, jffs2 doesn't support writable mmaps.

Maybe running it directly, rather than via init, will expose the problem? When running it directly it was sitting for a while and then exiting without any error (even in verbose mode). I should strace it. I would gdb it first and only if that turns out being hard, then try my luck with strace.
