sudo vs su

[voxik]

I am not sure wheter 'su' is the right choice, since in F18, there is possible to leave root account disabled. In that case, you are not able to use su, while sudo works just fine (that applies also for Ubuntu). May be we should detect if sudo is available on the system and use it in first place and fallback to su if sudo is not available.
