Bugzilla Bug 154729

The latest patch release of MythTV overwrites mythtv user's .bash_profile and
.xinitrc - without warning!

This new change means that it will overwrite any local changes made to these
files, and more bizarrely, it will try to launch evilwm, even though that is
not a dependency of the package.

Please either check to make sure its not overwriting any local files within the
mythtv home directory, or make it an optional extra, and not mandatory.

Even worse, this release requires you to have a writeable ~mythtv home
directory.  I run the frontenv under my own UID and my entry for mythtv looks
like this:

# grep myth /etc/passwd /etc/group
/etc/passwd:mythtv:x:103:27:added by portage for
mythtv:/dev/null:/usr/sbin/nologin
/etc/group:tty:x:5:mythtv
/etc/group:audio:x:18:mythtv,vdr
/etc/group:video:x:27:root,mythtv,vdr

I would recommend the elimination of this recent ebuild change:
>       insinto /home/mythtv
>       newins "${FILESDIR}"/bash_profile .bash_profile
>       newins "${FILESDIR}"/xinitrc .xinitrc

The user is a user created by the ebuild for the purpose of dropping privileges
from root which is the default insecure way of running MythTV. If you don't
like it, do something else. It's as is provided by the package. 

I don't have a problem with the mythtv user. I think you misunderstand.

What I am saying is that .xinitrc and .bash_profile files are configuration
files and should not be overwritten everytime an emerge happens, just like /etc
files aren't overwritten.

Also, the current .xinitrc file assumes that we have evilwm installed and wish
to use mythfrontend.

I personally use fvwm2 and mythwelcome on my setup, and having this overwritten
everytime I emerge mythtv is not very nice.

Seem to have found a solution to this.

echo 'CONFIG_PROTECT="/home/mythtv"' > /etc/env.d/10mythtv-config

Then run env-update. Maybe add this to the ebuild?

This new behaviour is also incompatible with environments (like mine) where
/home is NFS-mounted & the export isn't root-writeable.  The emerge naturally
fails at the point where ~mythtv is being populated with .bashrc and .xinitrc. 
Unless this step can somehow be made to run under the mythtv user account?

Fixed in mythtv-0.20_p12172. You will actually need to install the version
first, which will overwrite your bash_profile and xinitrc again. But from then
on out, it will protect those files.
