If you run the installer with 'biosdevname=0', it respects this setting: biosdevname is not active, and you get systemd persistent naming names for your network devices (https://fedoraproject.org/wiki/Features/SystemdPredictableNetworkInterfaceNames ). But the parameter is not passed into the installed system, so when you boot the installed system, biosdevname *is* active, and you get biosdevname names for your network devices instead - you have to know to manually edit the grub config file to add biosdevname=0 there too. It was noted during the F19 cycle that this inconsistency (which you got baked into F19, for free!) can cause various undesirable effects, so ideally we should keep things consistent, here.
Discussed in 2013-11-14 Blocker Review Meeting [1]. This was voted a AcceptedFreezeException. This setting should be consistent in the installer environment and in the installed system. We would accept a patch after freeze if self-contained and safe. [1] http://meetbot.fedoraproject.org/fedora-blocker-review/2013-11-14/
The patch is safe.

Does it set "biosdevname=1" also?
Yes, no matter what the value of the installer biosdevname boot option is, it is just passing it if it founds any.
