Subject: test: introduce overridable ARCH variable in run-qemu
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=bf97572bd5145a9e1192297a806dda94a3422de0;p=thirdparty%2Fdracut.git

test: introduce overridable ARCH variable in run-qemu

Allow specifying the architecture for `run-qemu`. E.g. this enables
running armhf containers on arm64 hosts.
