Hello. I'm currently running some services in a chroot() and they seem to want to access device nodes in $chroot/dev/ I've previously created the required device nodes with mknod(8) but it looks like this can cause problems. For example, after doing an upgrade from 5.2-RELEASE to 5.2.1-RC the /dev/random device changed its major number from 250 to 249 and named started complaining: Jan 31 10:58:08 vimes named[321]: entropy.c:280: unexpected error: Jan 31 10:58:08 vimes kernel: Jan 31 10:58:08 vimes named[321]: entropy.c:280: unexpected error: Jan 31 10:58:08 vimes named[321]: fcntl(4, F_SETFL, 4): Operation not permitted Jan 31 10:58:08 vimes kernel: Jan 31 10:58:08 vimes named[321]: fcntl(4, F_SETFL, 4): Operation not permitted Jan 31 10:58:08 vimes named[321]: could not open entropy source /dev/random: unexpected error After deleting $chroot/dev/random and recreating it with a new major number named started working as expected again. I am wondering what the best way to do this is in a way that doesn't require me to manually delete+recreate those device nodes every time I recompile the system? Should I for example look into mounting a devfs-filesystem on $chroot/dev/ ? -- Regards / Hilsen Eivind Olsen <eivind@aminor.no>
