[Solved]no possible root with su

[fanthom]

What I do understand though is that you don't want to work on this case

because this case wants to achieve goals which i find totally different from the original kiosk's one: running only one app (firefox) with root access permitted for guest.
i have nothing against kiosk mods but dont want to be involved in supporting 10+ additional projects as i have no time for this (wife, kids, friends, job, etc). that's why i have created 'User's modifications to the Kiosk ISO' category where users can help each other and convert Kiosk to anything they want (even media player) but without me being involved.

to be honest: kiosk modifications are tough due to several things: kernel limitations (iso9660 as the only supported filesystem, lack of virtual terminals), missing deps, sometimes even single files. i would rather suggest sticking to some other minimal projects like slitaz which has the same ISO size as kiosk but are more friendly for modifications as have less restrictions enabled by default.

Just to tell that this was possible without modifying anything, just installing sshd, and ssh root@localhost would do the trick ^^
