[X2Go-Dev] x2goserver packaging questions

[Mike Gabriel]

HI Orion,

I re-include x2go-dev, I hope that's ok.

Not necessarily needed. /me thinks about removing the compat commands  
completely, as they have been obsolete for more then 3 years now.

In some setups, the site admin may decide to leave it uninstalled. (Or  
rather: to uninstall it after it got pulled in via Recommends: field  
in /debian/control).

Also, removing x2goserver-extensions may ease the X2Go Server  
debugging in some occasions.

The -xsession package is only necessary for people providing a full  
screen desktop shell. For people providing SaaS the -xsession package  
is not needed.

And x11-common is normally not needed for X2Go functionality. We hook  
into the system's Xsession scripts (via symlinking), so that's why we  
depend on x11-common here.

Instead of x2goserver-fmbindings people can use x2go*bindings. Also  
site admins may not want to add desktop icon support for locally  
shared folders.

The -pyhoca package is deprecated. It stems from a time when I was to  
shy to add functionalty to the x2goserver core package when I needed  
it for pyhoca-gui. This shyness is obviously gone...

I will remove the x2goserver-pyhoca package in some future release  
completely. So ignore it.

Splitting out printing is a must IMHO as it creates a separate  
user:group (x2goprint:x2goprint).

Yeah. This can surely be improved.

As the x2goruncommand should be turned into Perl at some time later, I  
will be happy to accept a tested patch for this.
