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.

finit.c:
o New service and shell_service stanzas for finit.conf
o Run service_startup() before /etc/finit.d/ hooks
o Run service_monitor() at end of startup
helpers.c:
o Several new functions:
- print_desc() displays a service starting up
- print_result() shows if service started OK or not
- start_process() is used by the services framework
svc.c:
Generic API for managing svc_t structures
ipc.o:
TIPC based framework for communicating with the service monitor.
E.g., to relay (re)configuration signals from a Web/CLI
front-end via finit to one or many setup daemons, and back.
services.c:
Service monitor framework
strlcpy.c:
Secure strncpy() replacement from OpenBSD under the free ISC License.

Update license and copyright information details in all files.
Much cleanup by moving hard coded strings/data to #defines and using more
common default values for each such #define.
finit.c:
o Make sdown[], startx[] allocated strings by default NULL
o This fixes the issues where the shutdown handler segfaulted
o Add ability to handle NULL input to build_cmd() by allocating space
o Ignore kernel cmdline "quiet" if in debug mode
o Add support for "network" stanza in finit.conf
o Mount -n to skip removing /etc/mtab
o Call swapon to enable swap if enabled in /etc/fstab
o Cleanup /tmp, /var/run and /var/lock
o Move sig_setup() *after* mount, sig_init() otoh runs early
o Start initctl monitor before forking off startx/getty process
o The startx process is now the console process. Only a getty is
started when in debug mode. Otherwise only X is started if it
is properly setup in /etc/finit.conf
o NOTE: Currently X evdev does not work!
o Support for /usr/sbin/services.sh has been replaced with finit
now instead supporting builtin run-parts for /etc/finit.d/
helpers.c:
o Bug fixes in run_parts() and also added chdir(oldpwd) at bottom.
o New functions:
- getuser() similar to getgroup()
- cls() clear screen, only runs when not in debug mode
- set_procname() used to set name "console" on console process
- set_hostname() encapsulates /etc/hostname and sethostname()
signal.c:
o Split sig_setup() in two: sig_init() and sig_setup()
The former to be called as soon as possible, while latter is
supposed to run when the base filesystem is properly up.
o Remove hard coded distribution specific progress bar write()
o Add debug messages to do_shutdown()
o Remove any lingering sync files in sig_setup()
initctl.c:
o Add debug messages and a new default: case to catch stray runlevels

Cleanup device creation and initial mount by assuming that the kernel
has devtmpfs enabled. This is the default for most modern GNU/Linux
distributions. See http://lwn.net/Articles/331818/ for more info.
Also, since finit is targeted at deeply embedded systems hooks for the
BusyBox udev replacement, mdev has been added. If MDEV is defined in
the build it will take care of both hotplugging of devices and initial
setup of /dev

finit.c:
o Perform signal setup as soon as possible, no need to do any
mounting of /proc or /sys beforehand
o Move signal setup and callbacks to a file of its own
o Use more #defines for hard coded strings
o Use a more neutral default hostname
signal.c:
o New file, for setup and signal handlers
o Add support for SIGSTOP/SIGSTP and SIGCONT. This pauses finit
respawning of xinit/shell. Useful for, e.g., debugging
o Document each ignored and handled signal better
o Disable SIGUSR1 and SIGUSR2 for now, will be reenabled later

This is a followup to Olivier Blin's patch from 88ffb93 in that it
applies the same patch to finit-mod.c that is already in finit.c, or
finit-alt.c as it was called then.
Also, the optional --directisa argument to hwclock is not necessary.
The hwclock utility has a built-in fallback to use excplicit I/O over
the /dev/rtc in case the latter does not exist. See the hwclock(8) man
page for more information on this.

o Make finit-alt.c the new finit.c, save old finit.c as finit-org.c
o Keep original finit-alt.c for reference.
o Update README and ChangeLog with direction of this fork
o Correct ChangeLog date for v0.1 and set release date for
the 0.6-pre release to 20100614, which is the last commit
by the original author.
o Add standard LICENSE file for MIT License
o Add standard AUTHORS file to document history of project
o Bump version to 1.0-pre to distance fork from original

There is an issue with some ACPI/Kernel combinations to do with shutdown.
It isn’t always powering off (tried /proc/acpi and /sys methods) - however
removing all the fd > 5 stuff and putting in the simple line
“reboot(RB_POWER_OFF);” worked for all thus far. Although semantically
incorrect it is a working solution.

*) Add -march=pentium-m if compiling finit or finit-mod (as the target will
be an eeepc).
*) Add a -DNO_HCTOSYS make option that omits the first /sbin/hwclock if the
user has enabled CONFIG_RTC_HCTOSYS in the kernel.
*) Add a -DDIRECTISA make option to append –directisa to /sbin/hwclock lines
if the user has disabled CONFIG_GENRTC and enabled CONFIG_RTC but not
enabled CONFIG_HPET_TIMER and CONFIG_HPET_RTC_IRQ.
