[RFE] install from software raid in f7

[dragoran <drago01 gmail com>]

Hello,
Anaconda is able to install from harddisk. But this does not work if the 
images are on a mdraid device. (cannot select it).
Anaconda is able to mount md raid devices (see rescue mode). So is it 
possible to add this feature to f7? (point to md raid device and 
install/update from there).
This will not only make it possible to do harddisk installs fro people 
which does not have a non raid partiton on there disks (exept /boot 
which is to small), but this (raid0,raid5) would also be the fastest 
install source (comparing with non raid hdd or optical media).
