2016-02-11init: make the command-line rewrite optionalNicolas Carrier
When launched as PID 1 and after parsing its arguments, init wipes all all of them except argv[0] and rewrites argv[0] to contain only "init", so that its command-line appears solely as "init" in tools such as ps. This patch adds the FEATURE_INIT_MODIFY_CMDLINE which, if set to n, will make init preserve all its arguments including argv[0], be they parsed or ignored. The original command-line used to launch init can then be retrieved in /proc/1/cmdline on Linux, for example.

2016-02-01Fix compiling with musl's utmp stubsKylie McClain
This patch fixes compiling busybox with FEATURE_UTMP and _WTMP enabled. musl, while not really support utmp/wtmp, provides stub functions, as well as variables such as _PATH_UTMP, so that programs using utmp or wtmp can still compile fine. My reasoning for this patch is that on Exherbo, I'm currently trying to get us to be able to use the same busybox config file for both glibc and musl systems, using utmp/wtmp on systems that support it, and using the stubs on musl without needing two different configs. As of latest musl git, it provides all utmp functions needed; 1.1.12 doesn't, but I sent a patch to Rich to add the utmp{,x}name functions expected to exist, which was merged into musl upstream.

2015-04-02*: Switch to POSIX utmpx APIBernhard Reutner-Fischer
UTMP is SVID legacy, UTMPX is mandated by POSIX. Glibc and uClibc have identical layout of UTMP and UTMPX, both of these libc treat _PATH_UTMPX as _PATH_UTMP so from a user-perspective nothing changes except the names of the API entrypoints.

2013-11-26init: halt on SIGPWR tooBogdan Purcareata
Most init processes implement a handler for SIGPWR that gracefully stops all child processes when shutting down a machine. Some other technologies rely on this signal - e.g. Busybox powered LXC containers. This patch makes busybox init halt when receiving SIGPWR.

We store init actions forever. 256 bytes per action means that a typical inittab of ~10 commands uses 2.5k just to remember command strings - which are usually _much_ shorter than 256 bytes.
