I'm trying to run /usr/share/mythtv/contrib/ipodexport.pl script from within Mythtv backend as a user job.

But it fails with

Well, glad you got it... we never really had any input on anyone even using the perl stuff w/Myth so we just kinda slapped it in there, not knowing what anyone would do with it.

ha, ok. So does that mean you are looking into it? Much appreciated.

Yup! You are right. I JUST figured this out too, as you posted it, ha.

But the weird thing I didn't notice was that gentoo uses /etc/mythtv as the backend user's home dir. As stated in first post, I changed the passwd file to use home dir /home/mythtv so I originally copied the file there and it didn't fix the backend. So now I got it all straightened out.

copy a working config.xml to /etc/mythtv/.mythtv/config.xml
got it

Thanks so much! Now maybe the gentoo devs can fix this in the ebuilds.

yeah, think it did change. Believe it or not I've been running the same gentoo box for 7 years now. It started off with 2.4.something and mythtv .11. Over the years I've been upgrading it, now i'm running 2.6.25 and myth 0.21. Never rebuilt from scratch. So who knows whats on my system.

EDIT: I think as of mythtv 0.21 it required a home/shell login for the mythtv user. 0.20 did not.

I originally installed at 0.20.1. That definitely created the user with a home of /home/mythtv and that's always where my working .mythtv directory and config files have been. It appears that the ebuild creates /etc/mythtv but does nothing with it at all.

Note however that I've never actually set a password for the user, as nothing ever logs in directly as mythtv. The backend runs from the init script of course, and I have the frontend starting from /etc/inittab. If I ever want to manually run anything and mythtv I just do "su - mythtv" as root.

interesting

this is in my /etc/init.d/mythbackend:

Wow...you're 100% correct! Mine is exactly like that. It's always worked because the default database connection information is in fact what I'm using. If I ever trued to change the mysql login information I would have been going nuts.

That's hard to figure given that the original ebuild I installed created the mythtv user with a home /home/mythtv. I wouldn't be surprised if that goes back to some version where the mythtv user was created with no home.

In your case (trying to run the perl script as a user job from the backend) it would in fact be using that. I never ran into problems as I never ran any of the perl stuff from within the backend.

I wonder if it wouldn't be a decent idea to have that home defined in /etc/conf.d/mythbackend....just a thought.

So I recently started getting the same error from my optimize_mythdb cron job. However, it still seems to run. Am I safe ignoring this error?
