Is 'root' a guaranteed name?
misc/chroot-credentials.sh since v7.4-16-gc45c51f assumes so.
I'm still not convinced (and will look at addressing that separately).
Do we even need to treat root specially. Can we just drop explicit root entry?

Also why so many (100). The test is a bit slow and you would get
the same coverage from a couple of entries?

Better to:
echo 'option ...' > exp-err
compare exp-err err || fail=1

Minor point, but it's better to use '' quotes when not interpolating,
here and throughout the test.

:> out
thanks!
