# 1) setfacl maps ACLs into file permission bits if on "noacl" file systems.
#
# On file systems which do not support ACLs (e.g. ext4 mounted with -o noacl),
# setfacl operates on the regular file permission bits, and only fails if the
# given ACL spec does not fit into there.  Thus, to test if ACLs really work
# on the current file system, pass an ACL spec which can't be mapped that way.
# "Default" ACLs (-d) seem to fulfill this requirement.
#
# 2) setfacl only invokes the underlying system call if the ACL would change.
#
# If the given ACL spec would not change the ACLs on the file, then setfacl
# does not invoke the underlying system call - setxattr().  Therefore, to test
# if setting ACLs really works on the current file system, call setfacl twice
# with conflictive ACL specs.
