# mtools 4.0.49, part 1 of 3 — the shipped PAYLOAD and the OPTION surface.
#
# Part 2 (65-mtools-fmt.test) covers the codepage contract, mformat geometry and
# the device-level tools; part 3 (65-mtools-files.test) the file operations. All
# three emit mtools/* ids, so `brintos-selftest mtools` selects the whole surface;
# only the runner's 60 s per-suite wall-clock accounting is split — a three-way
# split rather than dosfstools' two because this surface is 184 cases and a
# process spawn costs ~0.5 s here.
#
# Every expectation was measured against a native mtools 4.0.49 built from the
# same tarball with the SAME configure answer this port needs
# (ac_cv_header_iconv_h=no --without-x --disable-floppyd) under LC_ALL=C, then
# re-measured on target. Two in this file are counter-intuitive enough that a
# suite written from expectation would have shipped false reds:
#   * mtools is ONE binary and every tool name is an argv[0] symlink onto it, so
#     unlike dosfstools' compat spellings the name it is invoked as SELECTS the
#     command — which is why -V reports the name rather than "mtools".
#   * `mshortname` with no arguments exits 0 while every other tool exits 1, and
#     `mtoolstest` exits 0 because it is a config dumper rather than a command.
