Hi, thanks for the patch.

First, user=$(env | grep USER | cut -d "=" -f 2) is equivalent to just user=$USER as far as I can tell. Which, combined with the next line is just equivalent to if [ "$USER" != "root" ] right?

But backing up a level, the skip_without_fuse is intended to catch this; is the

    capsh --print | grep -q 'Bounding set.*[^a-z]cap_sys_admin' || \
        skip "No cap_sys_admin in bounding set, can't use FUSE"

bit not working in your environment for some reason? What does capsh --print show?

user=$(env | grep USER | cut -d "=" -f 2) // Gets the current user of the system
if [ "$user" != "root" ] // Judge whether the current user is an ordinary user

of course, there are omissions in this way, the program is a relatively fast and simple repair program, if there is a better program, the trouble to pay attention to the guidance, thank you very much

Sometimes it makes sense to do:

USER=$(id -un)

I've come across platforms that don't set USER by default, but the technique here is more complex than it needs to be

then
skip "user:$user does not support running the test case"
fi

setup_test_repository "bare"

echo "1..12"
