This patch reverts back to the progress/status behavior of Finit < v3.0 because this is what most users expect, including the maintainer. The resulting code and configure script is a lot simpler to understand and maintain: - No more --enable-progress or --enable-progress-classic configure flags. Instead a progress_style variable in helpers.c that can be changed at compile time for those that really need it. - No more 'splash' kernel commnand line option. This turned out to be *very* confusing to many users who believed it was some sort of graphical splash screen à la Plymouth. Also, when Finit debug is enabled we now have a global 'debug' flag which now alo controls if klogctl() should be called to prevent the kernel logs to the console or not.

Tips & Tricks with the kernel cmdline
|
|
=====================================
|
|
|
|
This document summarizes the different boot parameters that can be
|
|
passed on the Linux kernel command line. Not limited to Finit.
|
|
|
|
* `debug`__
|
|
Enable kernel debug. Debug messages are printed to the console
|
|
until Finit starts up, the syslog daemon then empties `/dev/kmsg`
|
|
|
|
* `init=/bin/sh`
|
|
Bypass system default init and tell kernel to start a shell. Note,
|
|
this shell is very limited and does not support signals and has no
|
|
job control. Recommend using, and modifying, `rescue` mode instead.
|
|
|
|
* `panic=SEC`
|
|
By default the kernel does not reboot after a kernel panic. This
|
|
setting will cause a kernel reboot after SEC seconds.
|
|
|
|
* `quiet`
|
|
Suppress kernel logging to console, except for warnings and errors.
|
|
|
|
* `rescue`
|
|
Start Finit rescue mode; no network, no `fsck` of file systems in
|
|
`/etc/fstab`, no `/etc/rc.local`, no `runparts`. The configuration
|
|
is read from `/etc/rescue.conf`, can be modified by the operator.
|
|
|
|
* `single`, or `S`
|
|
Single user mode, runlevel 1, in Finit. Useful to debug problems with
|
|
the regular runlevel. All services and TTYs in `[1]` will be started,
|
|
so a `tty [1] @console nologin` configuration presents you with a
|
|
root console without login.
|
|
