a config file to determine what config file is used by default? really? I thought the symlink method was rather simple, it's in line with what systemd does (default.target for instance) and it doesn't need to parse 2 config files, just 1. >> Take a look for instance at netbook.

That is never a bug. It's also perfectly valid, as the xbmc package can be both an entire desktop as well as just an application. as a matter of fact, it's insane that doing `zypper in -t pattern tablet-applications` completely breaks your netbook desktop installation, as it is right now. At least this change will somewhat help to reduce that breakage. >> It also makes no sense to do a package %post, since, for instance, on >> netbook, it's quite likely that mcompositor is installed before >> mutter, and now your netbook image would start.... god knows what. >> >> So, I made the choice to switch from: >> >> `echo "session=/usr/bin/foo" >> /etc/sysconfig/uxlaunch" >> >> to >> >> `ln -sf gnome.desktop /usr/share/xsessions/default.desktop` >> >> which in itself is already better, since we're still allowing the >> config file to be used, and the user can override this choice, and >> we're not potentially messing up a config file. > > How is that better beside making it more complex by allowing things to be > done in different ways and thus increasing the the risk that 1 type of > settings overrides the other leaving the user (What user?

I was asked by several people to consider this, and frankly, it was high on my list of things to implement originally when we wrote uxlaunch. I think I implemented it in the right way, given the fact that I've given this code almost 2 years of thought. Perhaps you'd like to tell me how you would like this to work instead? I must have wasted my time if you're so strongly opposed to it... also, the last part of your sentence is just wrong. with this system in place, there is zero, none, no way whatsoever that the default system desktop changes on any system without someone going in and changing the 'default.desktop' symlink or editing the config file or something like that. That is in direct contrast to the old situation, where this exactly DOES happen. Just install a netbook image and `zypper in -t pattern tablet`.
