Am I allowed to create a Linux distro (GPL license), which will include also some proprietary software and distribute this distro to the third parties (license issues related to closed-source software are OK, the proprietary software cannot be licensed under the GPL compatible terms)?
It is clear that proprietary software is not compatible with GPL. On the other hand, the proprietary software always run in separate process and therefore according to my opinion it should not be considered a derivative work by the GPL terminology.
If not, is it legal (and morally correct) to install the software during the first run of the distro?
