But after I did I have been very happy with it.
It is possible you need more in /dev. My initramfs has much more than yours - though it is still quite small. I sort of stole it from somewhere. I think I took an initrd from somewhere expanded it an culled out what iI did not want. Busybox is still the bulk by volume, but that got me all the /dev /etc/ ... stuff I needed You can pull mine from http://www.picocomputing.net/files/initramfs/ _______________________________________________ Linuxppc-embedded mailing list Linuxppc-embedded@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-embedded
