Did you read


g-p-m should be able to detect this just fine and provide the  
appropriate error message; e.g. only show a popup "Cannot suspend -  
another user or system job is running and preventing this operation;  
do you really want to do it anyway?" if the user actively pressed a  
button in either the UI or on the system.

(I think what we may need is some way of gnome-power-manager to  
figure out what is holding the lock to give more intelligent  
feedback; maybe a GetExePathForLockHolders(out array String) call and  
then you can show that to the user maybe even couple with some  
fancy .desktop file search so you have an l10n name and icon to show.)

(Btw, you probably want yum itself (through a yum plug-in) to take  
the lock (it's not a problem if both PackageKit and Yum holds the  
lock) such that this works nicely even when using yum from the  
command line)
