feedback-stories tvheadend
I used to have tvheadend running in a odroid c1. lately I needed to do transcoding and the odroid c1 is too weak so I set it up in a proper machine. I do care about power consumption so I needed to figure out a way of having the machine hibernated while not watching the iptv but also being sure it wouldnt hibernate while streaming video. reboot-guard is what I needed since I did not want to deal with systemd inhibitor locks and dbus. I do have a background service that queries the tvheadend api. if there is a subscription or a recording going on it saves the info to a file that I'm monitoring with inotify watch. depending on the contents I tell reboot-guard to avoid hibernate or not. cheers.

Innnnnteresting! Thanks for sharing! By default, rguard only blocks poweroff, reboot, and halt targets ... did you have to uncomment hibernate.target
to get this to work for you? E.g.:
def reboot_guard_systemd_refusemanualstart(self, enforce=True, targets=[]):
"""Block/unblock entering targets by way of RefuseManualStart=yes/no."""
if not targets:
targets = [
'poweroff',
'reboot',
'halt',
# 'hibernate',
# 'hybrid-sleep',
# 'suspend',
]
reloadDaemon = False
for t in targets:
t += '.target'
if enforce:
if self.add_systemd_unit_start_block(t):
reloadDaemon = True
else:
if self.del_systemd_unit_start_block(t):
reloadDaemon = True
if reloadDaemon:
logging.debug("Reloading systemd via: systemctl daemon-reload")
if not ret(subprocess.call(['systemctl', 'daemon-reload'])):
logging.error("Unexpected error reloading systemd")
yeah I got hibernate working
