finit.conf:
Use this as /etc/finit.conf on a Debian 6.0 based system with X
installed and sysklogd instead of rsyslogd. Works.
services:
Alternative method for extending the finit boot procedure. Simply
place this script file in an /etc/finit.d/ directory. The script
uses the standard run-parts tool to chain load other start scripts.
helpers.c:
o New functions:
- run(): home grown system() replacement
- run_interactive(): display progress and status when called
o Bugfix start_process(), make sure to use same signal setup for
children as in run() and run_interactive(). Also, use execvp()
instead of execv() to allow searching $PATH for executables.
finit.h:
o Move signal specific code to new signal.h.
o Bypass verbosity setting to let echo() always print to screen.
finit.c:
o Make run_parts() the default, remove external deps, it works.
o Use run() and run_interactive() to speed up execution further
on embedded systems where forking is expensive.
o Kernel cmdline "quiet" should not close STDIO since this makes
it impossible to run some daemons and start scripts. Instead,
we let "quiet" toggle the finit verbosity setting.
o Remove kernel cmdline "--verbose" (Upstart compat), to be used
to enable verbose finit when kernel should be quiet.
o Setup kernel specific settings in /etc/sysctl.conf
o Fix D-Bus startup problems. Probably what caused X from not
working initially. Silly rabbit.
o Use system() workaround to start X, cannot get it to start
at all using run() or run_interactive() at the moment.
signal.h:
New file, header file for signal.c. Was about time.
signal.c:
Remove blocking of SIGCHLD from sig_setup(), instead we setup
SIGCHLD early in sig_init() to handle fork() in run() & C:o.
