Finit v4.3-rc2

Critical bug fix release. If you run a 32-bit target with GLIBC 2.34 you need to upgrade!

Note: system verbosity on console at start and shutdown has been
increased. Now the output of all commands is logged to the
system logger, for early services /dev/kmsg is used.

Also: please notice the updated support for enabling and disabling
kernel and Finit debug messages on the system console. Very
useful when debugging either of them, e.g., a kernel module.
For details, see cmdline.md.

Changes

• Support for overriding default runlevel from kernel command line. Any runlevel [1-9] may be selected, except 6 (reboot). Issue #261
• New command line option: finit.fstab=/etc/fstab.custom, with full support for mounting, mount helpers, fsck, and swapon/off, issue #224
• Support for special device /dev/root, which may not exist in /dev. Finit now looks up the matching block device for / in /sys/block/
• Loading modules no longer shows arguments in progress output
• Warning messages in progress output now in yellow, not red, issue #214
• initctl, new command line option -V,--version for ease of use
• New condition done for run task, issue #207 by Ming Liu, Atlas Copco
• Refactor parts of shutdown and reboot sequence for PREEMPT-RT kernels, by Robert Andersson, Mathias Thore, and Ming Liu, Atlas Copco
• Conditions for run/task/sysv status, e.g. run/foo/success and task/bar/failure. Issue #232, by Ming Liu, Atlas Copco
• Conditions for services, can be used to synchronize other stanzas:
  • service/foo/running
  • service/foo/halted
  • service/foo/missing
  • service/foo/crashed
  • service/foo/stopped
  • service/foo/busy
  • service/foo/restart
• initctl signal support, by Jörgen Sigvardsson, issue #225
• initctl cond get support to match cond [set | clear], issue #255
• [WARN] messages on console now printed in yellow, issue #214
• Network services now also stopped when going to runlevel 6 (reboot), not just runlevel 0 (shutdown) or 1 (single-user)
• When ifup is missing on the system, bring at least lo up at boot
• Log output from ifup -a (and ifdown -a), to syslog
• Avoid blocking PID 1 when starting SysV init scripts
• Allow custom pid: for SysV init scripts
• Document supported types of forking/non-forking services
• Auto-detect running in some common forms of containers
• Simplify shutdown/reboot when running in a container
• Log to stderr when running in a container w/o syslog daemon
• Add support for type:forking to services, already supported but with a very difficult pid: syntax, issue #223. Docs updated
• Support for setting global environment variables in finit.conf, please note: this also affects Finit itself, be careful!
• Extended environment variables for pre/post scripts, issue #189
• Document secret service option respawn, which bypasses the crash semantics, allowing endless restarts
• Document secret HOOK_BANNER, the first hook point before the banner
• New plugin: hook-scripts, allows run-parts(8) style scripts to run on any hook point. Contributed by Tobias Waldekranz
• initctl (reboot) falls back to -f when it detects it is in sulogin recovery mode, issue #247
• The bundled sulogin is no longer enabled by default, in favor of distribution versions. Enable with ./configure --with-sulogin
• Support args to sysv-like scripts, e.g. bridge-stp br0 start
• The modules-load plugin now skips all lines starting with # and ;. Furthermore, files in /etc/modules-load.d/*.conf are now read in lexicographic order and UNIX backup files (foo.conf~) are skipped
• The name:id tuple is now more consistently used in all log and debug messages instead of the basename of the command

Fixes

• Fix nasty 32/64-bit alignment issue between finit and its plugins, applicable to 32-bit targets with GLIBC 2.34 and later. External plugins must make sure to use, at least: -D_TIME_BITS=64
• Fix #215: disable cgroup support at runtime if kernel lacks support or does not have the required controllers (cpu)
• Fix #217: iwatcher initialization issue, by Ming Liu, Atlas Copco
• Fix #218: initctl matches too many services, by Ming Liu, Atlas Copco
• Fix #219: not all filesystems unmounted at shutdown, by Ming Liu, Mathias Thore, and Robert Andersson, Atlas Copco
• Fix #226: initctl shows wrong PID for crashing services
• Fix #227: reboot stalls if process stopped with [WARN]
• Fix #233: initctl shows wrong status for run/task, by Sergio Morlans and Ming Liu, Atlas Copco
• Fix #248: source env:file also in pre: and post scripts
• Fix #260: drop limit on device name in Checking filesystem...` output
• Fix start/stop and monitoring (restart) of SysV init scripts and forking services, see the updated documentation for details
• Fix call to swapoff at shutdown, does not support -e flag
• Fix suspend to RAM issue. Previously reboot(RB_SW_SUSPEND) was used, now the modern /sys/power/state API is used instead.
• Fix nasty run/task/service matcher bug, triggered by stanzas using the same basename of a command but different :ID. Caused Finit to match with already registered but different run/task/service
