thanks for digging into this: so it's really a subshell when running in ( . $script ) and maybe we can avoid this. > > i also found, that it is possible to simply change all calls to "exit" > > to a "return", so the sourcing of a script will be aborted and no > > subshell is needed anymore. > > > > this must be somehow "enforced" by the openwrt-build: all files in > > "/etc/hotplug.d/"* cannot have the keyword "exit" in there 8-) otherwise > > we break the execution of further calls in the loop... > > I agree with you.
