Good catch! Well /home/$user get's not mounted inside the chroot, but
you are right, the /etc/passwd is from chroot creation time? So
contains /home/$user thus returned by getpwuid($<)[7]? But then
/home/$user is removed from @paths by the above, as it really does not
exists.

If I'm right, then buildd's work like that, that building user has
no exiting home (we already fixed some bugs going in that direction).

Currently I have not a good idea how to proceed. :(
