Often the underlying problem would have been trivial to fix, if i had a way to access the rootfs. Patching bootmenu enables us to boot a minimal system with just usb network and sshd enabled. that's still not optimal because this solution relies on rootfs being accessible. why? - [http://www.mail-archive.com/maemo-developers@maemo.org/msg22365.html 1] [https://bugs.maemo.org/show_bug.cgi?id=6468 2] - in short, during boot process no seperate initrd is utilized - in fact the rootfs is misused for it -.- . the bootmenu script circumvents that by redirecting the pivot_root call issued by /sbin/preinit, which is a pretty dirty - yet effective hack. <i>hmmm... just an idea, but why not use the rootfs for initrd purposes only?...</i> | ||
sshd will be using settings from the rootfs. | |||
