I noticed that "test -r file" returns success when called as root for a file
with these permissions:
"--w-------" (see also https://stackoverflow.com/q/71435657/6607497)
The documentation simply states:
‘-r FILE’
True if FILE exists and read permission is granted.
Doing an strace it seems stat() is used to check the permissions (well, what
about ACLs, just in case?)
I think there should be a better explanatiomn how the permission tests work,
especially when called as "root".
