That's a bit surprising … In my (usr-merged) sid cowbuilder chroots,
I have (after installing iproute2) lots of options of calling ip(8),
among them /sbin/ip:

# ls -la /bin/ip /usr/bin/ip /sbin/ip /usr/sbin/ip
-rwxr-xr-x 1 root root 705432 Oct 24 14:24 /bin/ip
lrwxrwxrwx 1 root root      9 Oct 24 14:24 /sbin/ip -> ../bin/ip
-rwxr-xr-x 1 root root 705432 Oct 24 14:24 /usr/bin/ip
lrwxrwxrwx 1 root root      9 Oct 24 14:24 /usr/sbin/ip -> ../bin/ip

(And the tests run successfully in this chroot.)

I'm wondering if the test system misses the (/bin and) /sbin
symlink(s) into /usr? Or something else?

Of course looking for all of /bin/ip /sbin/ip /usr/bin/ip /usr/sbin/ip
or using File::Which etc. would fix this (except that I can't
reproduce the problem in the first place), but I'd like to understand
what's going on here …
 

Cheers,
gregor
