This adds a 'parse_envfile' function that reads files such as
/etc/locale.conf and /etc/vconsole.conf without sourcing them as bash
logic. Several benefits are realized from this:
- Impossible to execute arbitrary code
- Bad syntax won't prevent the entire file from being read
- Possible to limit what variables are allowed

The bash parser assumes that an expression continues when || is at the
end of a line.

This is not very useful, is not maintained, has open serious bugs. Better
to admit that it does not work and just remove it. Someone could easily
make an AUR package with a hook, if they want it and can make it work
as expected.
The only case where this would be useful is in case lvm monitoring is in use
and dmeventd sends out a message to syslog before syslog-ng is started
(there is a very small window). However, not even this works atm (as far
as I know) due to bugs in minilogd.

Read KEYMAP, CONSOLEFONT and CONSOLEMAP from vconsole.conf. If they are
set they take precedence over the values in rc.conf.

Since recent change in udev package [#1] (install: remove post-install)
In case of booting without initramfs and there is no /dev/null:
* if / is ro, devtmpfs mount will fail, in consecuence /dev will be mounted as tmpfs.
* if / is rw, devtmpfs mount will success, but a regular file /dev/null in / will be created.
[#1] http://projects.archlinux.org/svntogit/packages.git/commit/trunk?h=packages/udev&id=8728747c2b3d5d0506f7e6f1ac74edc0319591d6

Abstract out timezone setting into its own function, passing
Country/Area as a parameter. Do some menial checking to make sure:
- the zonefile actually exists, erroring when it doesn't
- /etc/localtime is a symlink to the correct zoneinfo file, relinking
when it isn't.

locale.sh parses rc.conf at runtime and sets the LOCALE accordingly,
rather than writing a static file at every boot.
This eliminates yet another write to /etc.

We still support a separate /usr if it was somehow mounted by the initrd.

We check for /usr/lib being present. If it is not, we assume /usr
is not yet mounted and warn.

Rationale
Currently we have to duplicate at least the mount /proc code line into a
custom sysinit_start hook to be able to start a splash daemon or something
in case no initcpio is used.
Moreover we want to make sure nothing can open files read/write on root
which would block the read-only remount.
So running the sysinit_start hook a bit later appears to be more save.

The rules should be:
* Use quotes when literal strings are involved.
* Use quotes when ever using a substitution which might produce blanks
as a possitional parameter unless word splitting is intended.
* Use quotes on the right hand side within '[[ = ]]'
unless pattern matching is intended.
* Don't use quotes for substitutions where not needed as in assignments.

Move it into a function to allow clean error detection of all steps performed
and also to be able to reuse this in rc.single.
|
|
Use correct patterns and get rid of the /dev/null redirection workaround needed when trying to remove '..'.
|
|
Revert to using in_array() instead of is_in_array() which actually doesn't exist.

There are only two possible situations:
a) /var/run is a symlink to /run: Conditional result is always 'false' even without checking /var/run/daemons (which doesn't exist).
b) /var/run is a directory: Conditional result is always 'true' because any symlink was removed when cleaning /var/run.
So following changes can be made:
* /var/run/daemons can be removed unconditionally because a symlink doesn't survive cleaning of /var/run anyway.
* The check whether /var/run/daemons is a symlink can be dropped because it has actually no effect.
Furthermore we can refactor to use the same conditional used for cleaning /var/run because we can't create the symlink if /var/run is not a directory.
|

Variables should be empty anyway here.
|
|
$FSCK_OUT/$FSCK_ERR might not be set when:
* unset in some custom sysinit_prefsck hook
* calling fsck() from a shutdown hook
|
|
This prevents sysinit_prefsck hooks from overwriting the value.
|
|
Genaral scheme for hook positions is now:
run_hook pre_foo
if [[$WE_WANT_TO_DO_FOO]]]; then
stat_busy "Doing foo"
if [[$PRECONDITIONS_FOR_FOO_NOT_SATISFIED]]; then
stat_fail
else
...
stat_done
fi
fi
run hook post_foo
rc.sysinit
-----------
run_hook pre_foo
[[$WE_WANT_TO_DO_FOO]] && status "Doing foo" foo
run hook post_foo
functions
------------
foo() {
[[$PRECONDITIONS_FOR_FOO_NOT_SATISFIED]] && return 1
...
}
Rationale
Following this scheme as close as possible (without duplicating code and status messages)
makes stuff more readable and uniform.
Splitting kill_everything() into two new functions stop_all_daemons() and kill_all() also
allows customization of either daemons stopping or process killing in an easy way.

|
The general rule is now: Align stat_{fail,done} with stat_busy
|
|
|
|
|
|
Also sanitze the PATH for rc.single, rc.multi, rc.local and daemons.
|
|
|
|
|
|
|
|
|
|
|
|
kill_everything
|
|
This avoids errors if one should set the noclobber shell option somewhere (within a daemon script or some custom function).
We already had this, but it seems gone lost mostly.
|
|
When using process substitution with status(), the resulting /dev/fd/* might get lost before it is actualy used. This happens in case a custom stat_busy() forks a subshell.
|
|
Note: The code
status "$text" $command > $file
writes nothing because there's a &>/dev/null within status().

To avoid setting the kernel timezone with an out-of-date /etc/localtime, we pass TZ
directly to hwclock.
Also document how TIMEZONE and HARDWARECLOCK are optional in rc.conf

be deleted on boot. Send them to /dev/null.

rc.single changes (when coming from multi-user):
* avoid settling UDev quietly as in rc.sysinit
* modules defined in rc.conf are loaded if missing
* minilogd is started before udevd as in rc.sysinit
rc.sysinit behaviour is unchanged
