Subject: tests: make docker.py check for persistent configs
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=43c898b75a3bb92b113f9a366a06cac013d055a8;p=qemu.git

tests: make docker.py check for persistent configs

binfmt_misc configured with the "F" flag opens the interpreter at
config time. This means it can use an already open file-descriptor to
run QEMU so there is no point trying to copy the binary into a
container.
