4 | # 5-second regression test for dump/verify/restore. It's not intended to be | |
5 | # an exhaustive regression test, just a quick way to verify that you haven't | |
6 | # introduced any errors when changing code. | |
7 | # | |
8 | # N.B., this only verifies that THIS build of dump(8) and THIS build of | |
9 | # restore(8) will play well together. It does not guarantee that these systems | |
10 | # are compatible with released versions of the software! For that we need | |
11 | # to keep images of known-good partitions and dump files. | |
