testmfs: catch MFS format changes
This test tests mkfs.mfs will generate the same FS image given the same
input files. mkproto creates a proto file (normalizing directory entry
order). The assumption is that a change in the output flags a tacit
change in FS format, and that a FS format change will cause the image
to change.
. Changes to mkfs.mfs that innocently change the format can
change the sha1 output in the script along with it.
. The assumption is that corresponding versions of mkfs.mfs and
MFS will always work together; otherwise a lot breaks (ramdisk etc.)
. Therefore, as long as a generated FS image stays the same with the
same input now, incompatible MFS changes will still be flagged,
even if they work together with the current mkfs.mfs.
testisofs: test ISO filesystem
. to test isofs: prepare an ISO FS image using writeisofs, copy it
to a RAM device, mount it using the iso9660fs server, compare the
SHA1 contents of the files on the ISO with the inputs.
. use su to run certain commands in the script as root
run script: run shell script tests
. they are installed without .sh so should be
searched for as such
. add diagnostic when tests are skipped
