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

Finit -- A reimplementation of the EeePC SysV init replacement "fastinit" ========================================================================= Finit is a reimplementation of the EeePC "fastinit" program based on its system calls with gaps filled with frog DNA. Finit's original purpose was to build upon the general workings of the EeePC fastinit and improve/optimize it for Xandros or alternative distributions running on the Eeepc. However, focus has now shifted to small embedded Linux systems and headless miniature servers with a need for extremely fast boot. Nevertheless, finit comes in three flavors: o finit-org is a replica of the Asus fastinit, o finit-mod is an improved drop-in replacement for fastinit, and o finit is a generic replacement for other systems. Finit-mod and finit (previously finit-alt) were much improved with patches from Metalshark. See the GitHub project's Wiki at https://github.com/troglobit/finit, or the original author's home page at http://helllabs.org/finit/ for more information. Usage scenarios --------------- 1. Provide an extremely fine tuned and fast boot on embedded systems or Linux distributions for the EeePC or other netbooks. (finit) 2. Replace the original Eeepc 702 fastinit (finit-mod) 3. Provide a reverse engineered document of the original EeePC fastinit implementation. (finit-org) Finit is distribution-specific. Currently it generates a finit-mdv executable for Mandriva 2008/2008.1 systems. Smurfy ported it to eeeXubuntu, and parts of his port have been merged to finit. Finit features -------------- Finit reads configuration information from /etc/finit.conf. See the source code for available options. Rebooting and halting --------------------- Finit handles SIGUSR1 and SIGUSR2 for reboot and halt, and listens to /dev/initctl so standard Linux reboot and halt commands should also work. Debugging --------- Add finit_debug to the kernel parameter line to enable trace messages and to run a shell after the X server.
