Subject: test: support systemd in target rootfs
X-Git-Tag: 109~38
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=62ee7e4ed7ac05335abd6945fa623df4b13e2eac;p=thirdparty%2Fdracut-ng.git

test: support systemd in target rootfs

The test-root module installs `test-init.sh` in `/sbin/test-init` and
adds `testsuite.service` if systemd is used. When systemd is used in the
target client/server rootfs, the systemd in the initrd hands over the
control to the systemd in the rootfs. Then `testsuite.service` executes
`test-init.sh` instead of the wanted client/server init scripts.

Add the helper function `inst_init` to override the init script from the
test-root dracut module.
