92*6f55dfa4SMax Reitz# in a sense always absolute paths, so such paths will never be combined with
93*6f55dfa4SMax Reitz# the path of the overlay. But since "image:base.$IMGFMT" is actually a
94*6f55dfa4SMax Reitz# relative path, it will always be evaluated relative to qemu's CWD (but not
95*6f55dfa4SMax Reitz# relative to the overlay!). While this is more or less intended, it is still
96*6f55dfa4SMax Reitz# pretty strange and thus not something that is tested here.
97*6f55dfa4SMax Reitz# (The root of the issue is the use of a relative path with a protocol prefix.
98*6f55dfa4SMax Reitz#  This may always give you weird results because in one sense, qemu considers
99*6f55dfa4SMax Reitz#  such paths absolute, whereas in another, they are still relative.)
