Unknown linux kernel command line arguments are passed through as arguments to init, unless they have a period in them. --- I'm trying to run a shell script inside User Mode Linux. I have an init wrapper that forks and attaches the child process to /dev/tty0, then waits for the child to exit. (I need to do this for ctrl-c to work, pid 1 has kill blocked and /dev/console has no controlling tty.) This wrapper uses the standard execvp(argv[1],argv+1) trick from detach/nohup/setsid and so on. It worked until I tried to run the production shell script, the name of which includes the build stage (which has a period in it), and like all the build shell scripts it ends in .sh. I get this:
UML running in SKAS0 mode Checking PROT_EXEC mmap in /tmp...OK Unknown boot option `/home/landley/newbuild/firmware-build/sources/scripts/1.0-tools-umlsetup.sh': ignoring System halted.
Which sucks.
