Well, such packages are supposed to fail Auto-QA, because they'd be
uninstallable ;)

AFAICT, "su" has a similar problem:

[corsepiu at beck ~] echo $PATH
/usr/lib64/qt-3.3/bin:/usr/local/bin:/usr/bin:/bin:/usr/local/sbin:/usr/sbin:/users/corsepiu/bin

[corsepiu at beck ~]$ su -l fedora
...
[fedora at beck ~]$ echo $PATH
/usr/lib64/qt-3.3/bin:/usr/local/bin:/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/users/fedora/bin

Note the locations of /bin and /usr/bin.

This causes malfunctions of programs which utilize arg[0] to determine the
position of directories they expect to find in a relative position to the
program's location (e.g. /usr/bin/foo expects to find ../lib/foodata/).

A real world case for such a package is rpmfusion's m2vmp2cut.
