We can assume that a service for which a watchdog timeout was triggered
is unresponsive to a clean shutdown. However, it still makes sense to
execute the post-stop cleanup commands that can be configured with
ExecStopPost=. Hence, when the timeout is hit enter STOP_SIGKILL rather
than FINAL_SIGKILL.

This is a minor fix because it's not a major issue, this fix just avoid
to get EINVAL error from sigaction(2).
There are two signals can not handled at user space, SIGKILL and
SIGSTOP even we're PID 1, trying to handle these two signals will get
EINVAL error.
There are two kinds of systemd instance, running as system manager or
user session manager, apparently, the latter is a general user space
process which can not handle SIGKILL. The special pid 1 also can not
do that refer to kernel/signal.c:do_sigaction().
However, pid 1 is unkillable because the kernel did attach
SIGNAL_UNKILLABLE to it at system boot up, refer to
init/main.c:start_kernel()
--> rest_init()
--> kernel_thread()
--> kernel_init()
--> init_post()
current->signal->flags |= SIGNAL_UNKILLABLE

With Linux 3.9 (commit a935eaecef2b209ad661dadabb4e32b7c9a9b924), the
Asus keyboard driver has changed to be more compliant to the symbol
signification. This has led to some issues with udev. In particular,
the XF86TouchpadToggle (a Fn key) does not work anymore on Asus X52J.
I found another similar patch which does not seem to have been ever
submitted/merged:
https://launchpadlibrarian.net/73337842/95-keymap.rules.patch
Find enclosed the patch containing both the launchpad patch and mine
into one file.

- print tab-separated values and header
- add memcpy() to fill the memfd, to produce real-world results

Also reworded a few debug messages for brevity, and added a log
statement which prints out the filter at debug level:
Journal filter: (((UNIT=sys-module-configfs.device AND _PID=1) OR (COREDUMP_UNIT=sys-module-configfs.device AND MESSAGE_ID=fc2e22bc6ee647b6b90729ab34a250b1) OR _SYSTEMD_UNIT=sys-module-configfs.device) AND _BOOT_ID=4e3c518ab0474c12ac8de7896fe6b154)

* baud rate is optional and unnecessary for virtual terminals
* term type is optional (default is 'linux' for virtual terminals
and 'vt102' for serial lines)
* long options are more user-friendly
... all this is supported since util-linux v2.20 (Aug 2011).

To get useful results you should however specify a much longer time on
the command line.

This way the measurements are not skewed by twoo short total measurement
times, and results become stabler.

Before, one the unit file was deleted, install_context_for_removal()
would refuse to look for symlinks. But we can remove dangling symlinks
anyway.
In principle, package installation/deinstallation scripts should do
that before the unit is uninstalled, but they don't always do. Also,
a user might have added additional symlinks manually.

Merge all ENABLE_TMPFILES conditionals into one, and merge two ENABLE_EFI
conditionals. Also make sure the .in files are always distributed.

The font-size was missing a unit so they were ignored. This patch sets
the unit to 'px' and adjusts the sizes a bit as the text got very small.
|

This will add another color to the legend called "Loading unit files"
Like the generators it will mark a part of the systemd bar indicating
the time spent while loading unit files.

--system is default anyway, and some poor user might type 9
characters without needing to.

Command changes current log level

systemctl set-default NAME links the default.target to the given unit,
get-default prints out the path to the currently set default target.

Since 11ec7ce, journald isn't setting the ACLs properly anymore if
the files had no ACLs to begin with: acl_set_fd fails with EINVAL.
An ACL with ACL_USER or ACL_GROUP entries but no ACL_MASK entry is
invalid, so make sure a mask exists before trying to set the ACL.

When an index key appeared in multiple sections (e.g.
CPUAffinity= was present in both "SYSTEM MANAGER DIRECTIVES"
and "UNIT DIRECTIVES"), when lxml was used, the key would
be not be displayed in all but one of those sections, and
only an empty <term/> element would be present. This
happens because lxml allows only one parent for each node,
and when the same formatted element was used in multiple places,
it was actually moved between them. Fix this by making a copy
of the element. The bug was present since lxml support was
introduced.
Also fix some indentation issues.

This partially reverts commit c3a170f3, which moved
efi_get_boot_timestamps too early in main(), before
/sys is assured to be mounted
Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=64371
[tomegun: in particular /sys/firmware/efi/efivars needs to be
mounted, which is not a problem if a systemd-initramfs containing
the correct module is being used. But not everyone uses an
initramfs...]

Unit names were mangled in function enable_unit only when dbus was
used. This patch adds mangling also when the dbus is not in use.
This makes it possible to say e.g.:
systemctl --root=/path enable cups
without spelling cups.service out in full.

POSIX_ME_HARDER mode is disabled for localectl. It doesn't
make much sense in case of localectl, and there's little reason

Patch resolves the problem that 'systemctl is-enabled' does
not work for templated units.
Without this patch, systemctl is-enabled something@abc.service
returned "No such file or directory", because it first checked
if /usr/lib/systemd/system/something@abc.service, etc. exists.
If systemctl is-enabled is called for templated units, this
check should be omitted and it should search for symlinks in
the .wants dirs right away.
This patch fixes the broken behaviour and resolves
https://bugs.freedesktop.org/show_bug.cgi?id=55318.
[zj: fixed the patch to still check for broken symlinks and
masked instances. Also removed untrue assumptions from
the patch description.]

Just calling service_enter_dead() does not kill any processes.
As a result, the old process may still be running when the new one is
started.
After a watchdog failure the service is in an undefined state.
Using the normal shutdown mechanism makes no sense. Instead all processes
are just killed and the service can try to restart.
