The intended use case is to use the mounted filesystem as input tree

@*
If CHRP equipment is detected, then modes @strong{cmd} and @strong{as_mkisofs}
issue some of the relaxation commands or options which get detected by
command @strong{-assess_indev_features}. This happens because CHRP firmware
reads file paths from file /ppc/bootinfo.txt and tries to find them
case-insensitively in the ECMA-119 tree without using Rock Ridge. If such a
path has actually forbidden properties, like the name "powerpc-ieee1275", then
the relaxations are needed to bring it unmangled into the ECMA-119 tree.
