Major release, support for conditions/dependencies between services, optional built-in watchdog daemon, optional built-in getty, optional built-in standard inetd services like echo server, rdate, etc.

Also, native support for Debian/BusyBox /etc/network/interfaces, overhauled new configure based build system, logging to /dev/kmsg before syslogd has started, massively improved support for Linux distributions.

Changes

  • Added basic code of conduct covenant to project

  • Added contribution guidelines document

  • Removed finit.conf option check DEV, replaced entirely by automated call to fsck for each device listed in /etc/fstab

  • Removed deprecated and confusing startx and user settings. It is strongly recommended to instead use xdm/gdb/lightdm etc.

  • Add support for initctl log <SVC>, shows last 10 lines from syslog

  • Add initctl cond dump for debugging conditions

  • Ensure plugins always have a default name, file name

  • Reorganization, move all source files to a src/ sub-directory

  • Add support for initctl <list|enable|disable> <SVC>, much needed by distributions. See doc/distro.md for details

  • Remove UNUSED() macro, mentioned here because it may have been used by external plugin developers. Set -Wno-unused-parameter instead

  • New table headings in initctl, using top style inverted text

  • Allow initctl show to use full screen width for service descriptions

  • New HOOK_BANNER for plugins to override the default banner()

  • Allow loading TTYs from /etc/finit.d

  • Improvements to built-in getty, ignore signals like SIGINT, SIGHUP, support Ctrl-U to erase to beginning of line

  • Add TTY nowait and noclear options

  • Allow using both built-in getty and external getty:

      tty [12345] /dev/ttyAMA0    115200              noclear vt220
  tty [12345] /sbin/getty  -L 115200 /dev/ttyAMA0 vt100
  tty [12345] /sbin/agetty -L ttyAMA0 115200      vt100 nowait

  • Silent boot is now the default, use --enable-progress to get the old
    Finit style process progress. I.e., --enable-silent is no more

  • Support for configure --enable-emergency-shell, debug-only mode

  • Support for a fallback shell on console if none of the configured TTYs can be started, configure --enable-fallback-shell

  • All debug messages to console when Finit --debug is enabled

  • Prevent login, by touching /etc/nologin, during runlevel changes

  • A more orderly shutdown. On reboot/halt/poweroff Finit now properly goes to runlevel 0/6 to first stop all processes.

  • Perform sync before remounting as read-only, at shutdown

  • Clean up /tmp, /var/run, and /var/lock at boot on systems which have these directories on persistent storage

  • Call udev triggers at boot, on systems with udev

  • Add missing /var/lock/subsys directory for dbus

  • Add support for poweroff

  • Add support for a built-in miniature watchdog daemon

  • Remove GLIBC:isms like __progname

  • Manage service states based on user defined conditions

  • Manage dependencies between services, w/ conditions (pidfile plugin)

  • Manage service dependencies on network events (netlink plugin)

  • Support for dynamically reloading Finit configuration at runtime

  • Refactor to use GNU configure and build system

  • New hooks for for detecting lost and started services (lost plugin)

  • External libraries, libuEv and libite, now build requirements

  • Early logging support to /dev/kmsg instead of console

  • Support for redirecting stdout/stderr of services to syslog

  • Support for managing resource limits for Finit and its processes

  • Add optional built-in inetd services: echo server, chargen, etc.

  • Add simple built-in getty

  • Greatly improved accounting support, both UTMP and WTMP fixes+features

  • Improved udev support, on non-embedded systems

  • Improved shutdown and file-system unmount support (Debian)

  • Support SysV init /etc/rc.local

  • Inetd protection against UDP looping attacks

  • Support systems with /run instead of /var/run (bootmisc plugin)

  • Adopted BusyBox init signals for halt/reboot/poweroff

  • SysV init compat support for reboot (setenv)

  • Compat support for musl libc

  • Add OpenRC-like support for sysctl.d/*.conf

  • Add support for Debian/BusyBox /etc/network/interfaces

  • Add support for running fsck on file systems in /etc/fstab

  • Added example configs + HowTos for Debian and Alpine Linux
    to support latest releases of both distributions

  • Lots of documentation updates

Fixes

  • Fix race-condition at configuration reload due to too low resolution. Thanks to Mattias Walström, Westermo
  • Fix to handle long process (PID) dependency chains, re-run reconf callback until no more applications are in flux. Thanks to Mattias Walström, Westermo
  • Clear reconf condition when initctl reload has finished
  • Skip automatic reload of /etc/finit.d/*.conf files when changing runlevel to halt or reboot
  • Fix issue #54: Allow halt and poweroff commands even if watchdog is enabled
  • Fix issue #56: Check existence of device before trying to start getty
  • Fix issue #60: initctl should display error and return error code for non-existing services should the operator try to start/stop them.
  • Fix issue #61: Reassert net/* conditions after initctl reload
  • Fix issue #64: Skip fsck on already mounted devices
  • Fix issue #66: Log rotate and gzip /var/log/wtmp, created by Finit
  • Fix issue #72: Check ifup exists before trying to bring up networking, also set $PATH earlier to simplify run() et al -- no longer any need to use absolute paths for system tools called from Finit. Thanks to crazy
  • Fix issue #73: Remove double ntohl() in inetd handling, prevents matches. Thanks to Petrus Hellgren, Westermo
  • Fix issue #76: Reap zombie processes in emergency shell mode
  • Fix issue #80: FTBFS on Arch Linux, missing stdarg.h in helpers.h, thanks to Jörg Krause
  • Fix issue #81: Workaround for systems w/o SYSV shm IPC support in kernel
  • Always collect bootstrap-only tasks when done, we will never re-run them. Also, make sure to never reload bootstrap-only tasks at runtime
  • Remove two second block (!) of Finit when stopping TTYs
