OK, this turned out to be easier after I spent some time reading through the /etc/rc.initdiskless script. All that was needed was to create: /conf/base/root /conf/base/tmp /conf/base/var And fill them with the files to be populated in a memory filesystem on reboot. A md_size file inside each dir tweaks the size of the memory disks according to the script. Then touch /etc/diskless and the magic happens! -- Jay L. T. Cornwall http://www.jcornwall.me.uk/
