I don't see why this should be logged at all, so let's delete it.

Hi all,

while working on another bug, I discovered the "strange" way systemd is
parsing Environment= in .service and thought it was worth documenting
(because I don't expect people to find this syntax by themselves unless
they read the parsing code ;)

Be more verbose about using space in Environment field and not
using value of other variables

[zj: expand and reformat the example a bit]

A watchdog notification may be handled after the watchdog timer was stopped
while stopping the service. As a result the timer is restarted and the
service may be restarted as well.
The watchdog timestamp is initially set during startup in
service_enter_start_post() and cleared when the timer is stopped. Therefore
it can be used as an indication if the timer should be reset.

For services without ExecStop= the state SERVICE_STOP is never entered. as
a result the watchdog timer is not stopped and the service is restarted (if
it is configuered to restart).
Stopping the watchdog timer for SERVICE_STOP_SIGTERM as well fixes this.

Using custom prefixes makes the whole build process a bit more
readable.

The idea is to make Makefile.am more declarative and avoid
repetitions. Redeclaring unit links as variables also makes
it easier to conditionally install only some of them.

This allows clients to get asynchronous notifications for user-requested
suspend/hibernate cycles. Kernel-triggered automatic suspending is not
covered.

This should make sure that closing the lid while shutting down won't
suspend the machine but will simply cause the shutdown to complete.

The fact that timeout=0 makes password agents wait indefinitely is documented
in http://www.freedesktop.org/wiki/Software/systemd/PasswordAgents. Document
it also in the relevant man pages.

In the x32 ABI, syscall numbers start at 0x40000000.  Mask that bit on
x32 for lookups in the syscall_names array and syscall_filter and ensure
that syscall.h is parsed correctly.

[zj: added SYSCALL_TO_INDEX, INDEX_TO_SYSCALL macros.]
