My opinion is averse. There's no valid reason to abandon the very simple
concept of users, groups, and permissions, just to have an "easy start" on
development (fixing apps later on is a PITA). If you don't care from
beginning, you'll end up where Vista is right now.
Where is the problem to chmod any file in /dev, /sys, etc. to do rdate, power
off, opkg etc (ok, for opkg I myself would prefer to be asked for root pw).
Or make apps SUID! Do we really have to repeat this annoyance yet *another*
If the user *really* wants to run these apps in the way you assumed (being
pissed off to relogin as root), why not use ageold mechanisms like sudoers,
To me it seems this is an *extreme* inattentiveness of developers, even worse
a ridiculous one.
