2014-08-03Unify parse_argv styleZbigniew Jędrzejewski-Szmek
getopt is usually good at printing out a nice error message when commandline options are invalid. It distinguishes between an unknown option and a known option with a missing arg. It is better to let it do its job and not use opterr=0 unless we actually want to suppress messages. So remove opterr=0 in the few places where it wasn't really useful. When an error in options is encountered, we should not print a lengthy help() and overwhelm the user, when we know precisely what is wrong with the commandline. In addition, since help() prints to stdout, it should not be used except when requested with -h or --help. Also, simplify things here and there.
2014-02-24virt: make Virtualization an anonymous enumThomas Hindoe Paaboel Andersen
This makes llvm happy when we assign an error code to the variable.
2013-11-06clients: unify how we invoke getopt_long()Lennart Poettering
Among other things this makes sure we always expose a --version command and show it in the help texts.
2013-10-31virt: move caching of virtualization check results into detect_vm() and ↵Lennart Poettering
detect_container() After all, we ended up calling detect_container() more often than detect_virtualization(), hence the former one should cache the results, since the latter is only a wrapper around the former.

Yay, we now have a completely generic systemd. No distribution specific checks anymore!
