hmm .. currently I adapt Slitaz as my own free "receptor muse" ;-) .. or something like Live music performance device (powered by slitaz/FSTHost). I have package with FSThost, improved sudo-pam, wine-rt and I'll soon package rtirq, set_rlimits etc... I still waiting for answer in Devel forum how add this to official repository.
Meantime I report bug to busybox because su/sulogin are not respect PAM even if it compiled in. (actually only busybox "login" respect PAM ;-)
There is a lot of work - so all helping hands are appreciated.
