Solution about hibernate when multiple OS is installed.

[Sławomir Lach]

There is discussion about this topic:
https://bugzilla.suse.com/show_bug.cgi?id=1180582

Basically, when use some filesystem and hibernate, then start another system, 
many bad things could happen. Currently, grub automatically starts hibernated 
OS, but there could be cases, when this is no sufficient.

Nobody need filesystem failure or data lost or other error causes running 
another OS than hibernates our PC, when it was powered off lately.

Solution could be different. First is to deny to hibernate, when there is 
another OS installed. Second could be only warn, when user try to hibernate.

You could probably solve it by deny to hibernate, but warn message is rather 
related to DE. If you decided best solution is to warn, I will send this 
message to KDE/GNOME/other DE mailing lists.

This mail was send there, cause Thomas Renninger's suggestion. This suggestion 
occur in linked discussion.

Best regards,
Lach Sławomir.
