92 | # Note that we could also do the same test with BASE_IMG=file:image:base.$IMGFMT | |
93 | # -- but behavior for that case is a bit strange. Protocol-prefixed paths are | |
94 | # in a sense always absolute paths, so such paths will never be combined with | |
95 | # the path of the overlay. But since "image:base.$IMGFMT" is actually a | |
96 | # relative path, it will always be evaluated relative to qemu's CWD (but not | |
97 | # relative to the overlay!). While this is more or less intended, it is still | |
98 | # pretty strange and thus not something that is tested here. | |
99 | # (The root of the issue is the use of a relative path with a protocol prefix. | |
100 | # This may always give you weird results because in one sense, qemu considers | |
101 | # such paths absolute, whereas in another, they are still relative.) | |
