Hi Everyone,.. I have just upgraded to mythbuntu 16.04,.. and everything works fine, other than I have to do a myth-backend restart when booting has finished because the TBS tuner cards were not ready soon enough,....

I see in the myth-backend service stuff there are statements that can pause execution until complete,.. eg After=mysqld.service network.target

so a system waits for mysql and networking to start,...

So,... is there an equivalent command to wait for the TBS driver to complete,.... before progressing to start myth-backend

eg After=TBS-Drivers,.. or something,.. can anyone help me here

Many thanks

Well I have found that

After=dev-dvb-adapter0-frontend0

is accepted within the myth-backend startup,... but this I feel is not the complete answer.... as the backend still needs a restart...

Maybe need something that notifies when all the drivers have been successfully loaded..
or maybe an After stanza for each tuner..

Can anyone help???

well tried the following stanza's...

and although not rejected on syntax etc.,... they did not stop the backend starting too soon

After=dev-dvb-adapter0-frontend0.device
After=dev-dvb-adapter1-frontend0.device
After=dev-dvb-adapter2-frontend0.device
After=dev-dvb-adapter3-frontend0.device
After=dev-dvb-adapter4-frontend0.device
After=dev-dvb-adapter5-frontend0.device

Back to the drawing board....

I found the answer here:-

1st edit the udev/rules.d 99-... file with the following,....

#
# Create systemd device units for capture devices
#
SUBSYSTEM=="video4linux", TAG+="systemd"
SUBSYSTEM=="dvb", TAG+="systemd"

The reason it did not work initially for me,.. is that it is a two step process...

the /lib/systemd/system/myth......service file needs

[Unit]
Description=MythTV backend service
Wants=mysql.service dev-dvb-adapter0-frontend0.device dev-dvb-adapter1-frontend0.device dev-dvb-adapter2-frontend0.device
Wants=mysql.service dev-dvb-adapter3-frontend0.device dev-dvb-adapter4-frontend0.device dev-dvb-adapter5-frontend0.device
After=mysql.service dev-dvb-adapter0-frontend0.device dev-dvb-adapter1-frontend0.device dev-dvb-adapter2-frontend0.device
After=mysql.service dev-dvb-adapter3-frontend0.device dev-dvb-adapter4-frontend0.device dev-dvb-adapter5-frontend0.device

Adding,.. then the file saving to /etc/systemd/system/myth.......service
NB the lib and etc difference....
