Now regarding some steps in the creation of the rootfs: use "tmpfs" for cases where a writable file system is needed and add the following lines to the /etc/rc.sh script: # mount TMPFS because root-fs is readonly /bin/mount -t tmpfs -o size=2M tmpfs /tmpfs create the same symbolic links for device files that must be placed in a writable filesystem: dev/ptyp0 → /tmpfs/dev/ptyp0 dev/ttyp0 → /tmpfs/dev/ttyp0 dev/ptyp1 → /tmpfs/dev/ptyp1 dev/ttyp1 → /tmpfs/dev/ttyp1 dev/ptyp2 → /tmpfs/dev/ptyp2 dev/ttyp2 → /tmpfs/dev/ttyp2 dev/ptyp3 → /tmpfs/dev/ptyp3 dev/ttyp3 → /tmpfs/dev/ttyp3 dev/ptyp4 → /tmpfs/dev/ptyp4 dev/ttyp4 → /tmpfs/dev/ttyp4 dev/ptyp5 → /tmpfs/dev/ptyp5 dev/ttyp5 → /tmpfs/dev/ttyp5 dev/ptyp6 → /tmpfs/dev/ptyp6 dev/ttyp6 → /tmpfs/dev/ttyp6 dev/ptyp7 → /tmpfs/dev/ptyp7 dev/ttyp7 → /tmpfs/dev/ttyp7 dev/ptyp8 → /tmpfs/dev/ptyp8 dev/ttyp8 → /tmpfs/dev/ttyp8 dev/ptyp9 → /tmpfs/dev/ptyp9 dev/ttyp9 → /tmpfs/dev/ttyp9 dev/ptypa → /tmpfs/dev/ptypa dev/ttypa → /tmpfs/dev/ttypa dev/ptypb → /tmpfs/dev/ptypb dev/ttypb → /tmpfs/dev/ttypb dev/ptypc → /tmpfs/dev/ptypc dev/ttypc → /tmpfs/dev/ttypc dev/ptypd → /tmpfs/dev/ptypd dev/ttypd → /tmpfs/dev/ttypd dev/ptype → /tmpfs/dev/ptype dev/ttype → /tmpfs/dev/ttype dev/ptypf → /tmpfs/dev/ptypf dev/ttypf → /tmpfs/dev/ttypf tmp → /tmpfs/tmp var → /tmpfs/var dev/log → /var/log/log In case you use dhclient also: etc/dhclient.conf → /tmpfs/var/lib/dhclient.conf etc/resolv.conf → /tmpfs/var/lib/resolv.conf Shall I create the symlinks manually? Is rc.sh executed ?? I,ve created a tmpfs directory in my rootfs directory and even if I mount it on my host it's not populateed. place the corresponding directories and device files in the tmpfs file system, the following code is added to the /etc/rc.sh script: mkdir -p /tmpfs/tmp /tmpfs/dev \ /tmpfs/var/lib/dhcp /tmpfs/var/lock /tmpfs/var/run while read name minor do mknod /tmpfs/dev/ptyp$name c 2 $minor mknod /tmpfs/dev/ttyp$name c 3 $minor done <<__EOD__ 0 0 1 1 2 2 3 3 4 4 5 5 6 6 7 7 8 8 9 9 a 10 b 11 c 12 d 13 e 14 f 15 __EOD__ chmod 0666 /tmpfs/dev/* Cristian
