Ping? Assuming it works (as in, if it passes, and if it correctly fails when you tweak the code to break it), could you commit it?

If you're happy with it, I will. I was just waiting for ngie to review it.

On on vacation now; I'll get to this sometime next Wednesdayish.

General comments:

• Use atf_check copiously to make sure that commands complete successfully.
• Use mkdir -p a/b instead of mkdir a; mkdir a/b .

usr.sbin/fstyp/tests/fstyp_test.sh

9–10

• mkdir -p dir/emptyfile
• This should use atf_check to make sure the command executes cleanly

21–22

Same as above

[asomers]

Address ngie's feedback. Use atf_check on almost every line except the ones
that need to redirect stdout, and condense "mkdir foo; mkdir foo/bar" to "mkdir
-p foo/bar".

Fix permissions on fstyp_test.sh

All references to zcat should use bzcat for portability..

The extra diffs in this file are caused by svn r284589, which went in after I opened this review. I didn't actually change this file in diff 6926

usr.sbin/fstyp/tests/fstyp_test.sh

Whoops! I'm surprised that worked at all. I think I started working with gzipped images then switched to bzip2 for better compression. Fix on its way...

Ping? Does my latest revision fix all review comments?

LGTM -- thanks for all the hard work :)!
