I currently have a busybox based embedded linux system. The filesystem is a readonly mounted jffs2 filesystem. One problem I've run into is that
/etc/resolv.conf can't be updated by DHCP.
Is it possible to use a different file than
/tmp is mounted as tmpfs).
Or am I being overly paranoid in mounting JFFS2 as read only? The root filesystem is read only because I don't want to wear out the flash.
