Feature request: Sleep delays with halt/reboot

upnort · 04-22-2018, 02:26 PM

Pat,

In the rc.d scripts could we do away with the sleep delays when shutting down or reooting? If the delays remain important for edge cases and older hardware, how about defining the delay times in something like /etc/default/sleep-delay?

Thanks.

P.S. Yes, I can manually edit the delays and have done so for many years. Just trying to offer a more elegant solution for all users.

Since you can just add a "0" to the end of a shutdown command to make it do it "now" (which you could also add) I don't see the benefit to the community at large. The reason for the delay isn't just for edge cases - it is to allow time for notification to go out to users and also lets you change your mind and cancel it.

The request is to make the time periods configurable rather than hard-coded to five seconds.

What time period is hard coded to 5 seconds?

The wait times in the Slackware shutdown scripts.

In rc.K there are three five-second sleep loops. There is a five second delay embedded in $FUSER_DELAY.

In rc.6, $FUSER_DELAY=5, there is /bin/sleep 5 for SIGTERM and PCMCIA, sleep 2 for DHCP, /bin/sleep 3 after running sync.

I am ONLY requesting the delays be configurable by users. The defaults would remain the same.

I suggested /etc/default/sleep-delay. Perhaps a file name of /etc/default/shutdown-delay is more appropriate or just /etc/default/shutdown, which could look something like this:

Code:

FUSER_DELAY=5
PROCESS_HANG_UP_DELAY=5
PROCESS_SIGTERM_DELAY=5
PROCESS_SIGKILL_DELAY=5
PCMCIA_DEACTIVATE_DELAY=5
DHCP_DELAY=2

In rc.K and rc.6, as appropriate, add the following:

Code:

# Default shutdown delay values:
FUSER_DELAY=5
PROCESS_HANG_UP_DELAY=5
PROCESS_SIGTERM_DELAY=5
PROCESS_SIGKILL_DELAY=5
PCMCIA_DEACTIVATE_DELAY=5
DHCP_DELAY=2
# Let users modify the default values:
if [ -r /etc/default/shutdown ]; then
  . /etc/default/shutdown
fi

Rather than for loop in 0 1 2 3 4 5, perhaps something like:

Code:

DELAY=0
while [ $DELAY -lt $PROCESS_HANG_UP_DELAY ]; do
  sleep 1
  echo -n "."
  DELAY=$(($DELAY + 1))
done
