install /dev/null as the new file instead of creating an empty file via
a no-op process substitution.

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

This keeps the functionality, but disables it by default.
Individual scripts/functions can turn it on if they want.

Assume that a shutdown executable has been created in /run/initramfs
by either dracut or mkinitramfs. Setup /run/initramfs to be a new root
and pivot into it. Making sure that nothing is using our old root anymore.
In particular this means we have to reexec init in the new root and
make sure stdio is using the new /dev/console.
This is inspired by Harald Hoyers work for systemd as well
as Thomas Bächlers deinitramfs.

This add a /etc/tmpfiles.d inside makefile to automatically create directory with package.
/etc is a better place to store user specific tmpfiles config where /usr/lib is better
for shipped with package config.
As Dave as already included this path inside his arch-tmpfiles, it would be a shame to miss out.

Make it clear that the message refers to network settings, as some

Categorize actions as 'create' or 'remove', for finer control.

Introduces the checkparams functions, which thoroughly checks arguments
for presence, length, and some amount of data validation.

This is the same concept as systemd's tmpfiles handling, slightly
simplified to avoid timed re-triggering of file cleaning. Most of our
current file cleaning that takes place in rc.single and rc.sysinit is
replaced by this, with the exception that we hold onto the /var/lock and
/var/run for finer control, since we still check for the possibility of
these directories being symlinks and adjust accordingly.

Rationale
Avoid printing any start hook status messages above the head line.
|
|
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.

This avoids trouble because of stale /run/daemons/* files.
|
|
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 '..'.
|
|
For checking whether a daemon is started via the DAEMONS array we use ck_autostart() now.
So make in_array() generic as the name suggests instead of removing '@'-prefixes from array members behind ones back.
Suggested-by: Dave Reisner <d@falconindy.com>
|
|
This is just a bit simpler.
in_array() should be fixed to be non daemon specific in a later patch.
|
|
Revert to using in_array() instead of is_in_array() which actually doesn't exist.
|
|
|
|
No need to set $PATH any more now that is in functions
|
|
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.

Currently $NETFS is used only for fsck and mount in rc.sysinit.
Since we moved it into functions, we can use it in netfs too to get rid of redundancy.
functions:
* Move 'nosysfs' from $NETFS into the mount -a type list because thats obviously the only meaningfull place.
* Add 'nofuse.glusterfs' to $NETFS to match the lists in netfs.
* Remove all 'no'-prefixes from $NETFS to make it more useful and readable.
* Add 'no'-prefixes to fsck and mount -a commands by parameter substitution.
netfs:
* Instead of the literals use $NETFS from functions which contains the same types now
|
|
Get rid of simple if-clauses and provide meaningfull exit code.
Maybe someone wants to abort suspend to disk/ram or something if umount fails
or even start this in a loop.
|
|
We set $PATH in functions now, so use it.
|
|
|
|
killall5 returns 2 if it didn't find any processes to send to. Using this avoids sleeping longer than needed. This saves another up to six seconds of reboot/shutdown/go-single time.
|
|
The exit code returned by the given command might be useful/expected, so don't discard but return it.
|
|
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.

Now that we set PATH in functions, we can use is everywhere.
|
|
Prevent any word splitting where not intended.
|
|
Braces are not needed in this case as a variable name can not begin with a number.
|
|
The general rule is now: Align stat_{fail,done} with stat_busy
