Hi,
The problem is that during init process, PATH is not set...
so it try to launch p4d (can't find it) but as it did the start statement it returns 0 as exit code so for Linux that's OK even if the process doesn't run
to correct that, just add the complete path to p4d, for example: /usr/bin/p4d -r $P4ROOT -J $P4JOURNAL -L $P4LOG -p $P4PORT -d
