This upgrade was done with minimum downtime and maximum revert-ability in mind. All package building is done BEFORE the point of no return, so if there are any build problems, they will be discovered while the previous version is still running.

While MythTV is still running
Go through these steps while your MythTV system is still working
Back up previous mythtv packages
- Package up existing mythtv in case you need to revert back:
quickpkg media-tv/mythtv x11-themes/mythtv-themes
- Package up mythtv plugins (Optional):
quickpkg media-plugins/mythbrowser media-plugins/mythdvd media-plugins/mythgallery media-plugins/mythmusic media-plugins/mythvideo
Build new packages (portage)
Note: the 0.20 ebuild in portage does not work, yet, so I am trying the overlay method
- Add mythtv and mythtv-themes to the packages.unmask file
echo "media-tv/mythtv" >> /etc/portage/packages.unmask echo "x11-themes/mythtv-themes" >> /etc/portage/packages.unmask
- Build the packages (but don't install yet):
emerge -B mythtv emerge -B mythtv-themes
Build new packages (overlay)
- Download the mythtv portage overlay from http://xxx.teppic.homelinux.net/MythTV-0.20-Overlay.tar.bz2
- Extract the overlay to your local portage overlay (/usr/local/portage). You should find that it creates an x11-themes, media-tv and media-plugins directory.
- Check your use flags (I noticed that the ivtv flag is new this version)
# emerge -ptvB mythtv [ebuild U ] media-tv/mythtv-0.20 [0.19_p9163-r1] USE="X%* alsa dvd ivtv%* lirc mmx opengl oss%* v4l%* vorbis%* (-altivec) -arts -backendonly -dbox2 -debug -dvb -frontendonly -ieee1394 -jack -joystick -lcd -xvmc (-oggvorbis%*)" VIDEO_CARDS="nvidia -i810 -via" 0 kB [1]
- Build the packages (but don't install yet):
emerge -B mythtv emerge -B mythtv-themes
With MythTV Stopped
This is the point of no return. Make sure you have some time set aside just in case you run into trouble, or if you won't be in trouble if you miss a few recordings.
Install new packages
- Stop Mythbackend
/etc/init.d/mythbackend stop
- Back up database:
mysqldump -u mythtv -p mythtv mythconverg > mythconverg-`date +%F`.sql
