### Changes
|
||||
- Add support for service `notify:pid` and `readiness none` global
|
||||
option to change how Finit expects readiness notification, issue #386
|
||||
|
||||
### Fixes
|
||||
- Fix #383: dbus and runparts regression in Finit v4.5. The configure
|
||||
script must expand `FINIT_RUNPATH_` before defining it in `config.h`
|
||||
- Fix #384: service environment variables drop everything but the first
|
||||
argument, e.g., `VAR="foo bar qux"` drops everything but `foo`
|
||||
- Fix #385: internal conditions, e.g., `<int/bootstrap>` turn into flux
|
||||
when leaving bootstrap, causing depending services to stop
|
||||
- Fix #387: global environment variables declared with `set VAR=NAME` do
|
||||
not drop leading `set `, causing `'set VAR'='NAME'` in env.
|
||||
- Sanity check environment variables, for services and globally. Ensure
|
||||
the variable name (key) does not contain spaces, or a leading `set `

- Update documentation for run/task shell limitations, issue #376

- Update documentation regarding automount of `/run` and `/tmp`

- Update plugin documentation, add section about limited tmpfiles.d(5) support

|

- Fix #372: lost `udevadm` calls due to overloading

- Adjust final `udevadm settle` timeout: 5 -> 30 sec
|
||||
- Fixed dbus plugin, the function that located `<pidfile> ...` in the

- The `runparts` executor now skips backup files (`foo~`)
|
||||
- The `runparts` stanza now properly appends ` start` to scripts that

start with `S[0-9]+`. This has been broken for a very long time.
|

- Fix #377: expand service `env:file` variables, allow constructs like:

- Fix #378: add run/task support for `<!>` to allow transition from

|

- Fix #382: do not clear `<service/foo/STATE>` conditions on reload.
|
||||
Introduced back in v4.3-rc2, 82cc10be8, the support for automatic
|
||||
service conditions have had a weird and unintended behavior. Any
|
||||
change in state (see `doc/svc-machine.png`) caused Finit to clear
|
||||
out *all* previously acquired service conditions.
|
||||
|
||||
However, when moving between RUNNING and PAUSED states, a service
|
||||
should not have its conditions cleared. The PAUSED state, seen
|
||||
also by all conditions moving to FLUX, is only temporary while an
|
||||
`initctl reload` is processed. If a service has no changes to be
|
||||
applied it will move back to RUNNING.
|
||||
|
||||
Also, we cannot clear the service conditions because other run/task
|
||||
or services may depend on it and clearing them would cause Finit to
|
||||
`SIGTERM` these processes (since they are no longer eligible to run).

|

1. Prepare emergency shell, if enabled
|
||||
2. Set up initial signal handlers
|
||||
3. Set up default $PATH early
|
||||
4. Mount `/proc` and `/sys`
|
||||
5. Check kernel command line for `debug` to figure out log level
|
||||
6. Load all `.so` plugins
|
||||
7. Call `fsck` on file systems listed in `/etc/fstab`
|
||||
8. Populate `/dev` using either udev or mdev, depending on system type
|
||||
9. Parse `/etc/finit.conf`
|
||||
10. Start built-in watchdog, if enabled and `WDT_DEVNODE` exists. This
|
||||
means any WDT that requires a kernel module need to be either
|
||||
compiled into the kernel, or insmod'ed in `/etc/finit.conf`

||||
11. Load all `/etc/finit.d/*.conf` files and set hostname
|

12. Remount `/` read-write if `/` is listed in `/etc/fstab` without `ro`
|
||||
13. Call 1st level hooks, `HOOK_ROOTFS_UP`
|
||||
14. Mount all file systems listed in `/etc/fstab` and swap, if available.
|
||||
On mount error `HOOK_MOUNT_ERROR` is called. After mount, regardless
|
||||
of error, `HOOK_MOUNT_POST` is called
|

15. Enable SysV init signals

et al. (Supports all locations that SysV init does.), handled by

`procps` plugin
|

19. Start all 'S' runlevel tasks and services
|
||||
20. Bring up loopback interface and all `/etc/network/interfaces`, if
|
||||
the `.conf` setting `network <SCRIPT>` is set, it is called instead
|
||||
21. Call 3rd level hooks, `HOOK_NETWORK_UP`
|
||||
22. If `runparts <DIR>` is set, [run-parts(8)][] is called on `<DIR>`
|
||||
23. Switch to the configured runlevel from `/etc/finit.conf`, default 2.
|
||||
At every runlevel change all `*.conf` files in `/etc/finit.d/` are
|
||||
(re)loaded and new services, tasks, and blocking run commands are
|
||||
started. Provided they are allowed in the new runlevel and all of
|
||||
their conditions, if any, are set.
|
||||
24. Call 4th level hooks, `HOOK_SVC_UP`
|
||||
25. Call `/etc/rc.local`, if it exists and is an executable shell script
|
||||
26. Call 5th level (last) hooks, `HOOK_SYSTEM_UP`
|

27. Start all configured TTYs
|
||||
|
||||
In (19) and (23) tasks and services defined in `/etc/finit.conf` and

`/etc/finit.d/*.conf` are started.

way they please. There are other hook points available, for more on
