pbuilder requires root to install the packages inside chroot to
satisfy dependencies, and to actually move into the chroot.
To be able to satisfy build-dependencies without root privilage,
one will need to run dpkg with a different target than /,
which in turn requires postinst scripts to run with a different
target than /. I've started writing "fakechroot" to try and run dpkg with
a different root directory by overriding libc functions, but it isn't yet
working fully, and it's probably going to take a pretty long time,
because there is a lot of functions to override.
pbuilder tries to switch to a normal user privilage inside the chroot,
and run fakeroot inside it, if you specify that in the pbuilder config file.
