Subject: tests: Add pathological iso9660 filesystem tests
X-Git-Tag: grub-2.12-rc1~131
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3ddd8e8ad4392f395117f657a317ff091cf59839;p=thirdparty%2Fgrub.git

tests: Add pathological iso9660 filesystem tests

These are not added to grub-fs-tester because they are not generated and
none of the filesystem tests are run on these ISOs. The test is to run the
command "ls /" on the ISO, and a failure is determined if the command
times out, has non-zero return value or has any output.
