FreeNAS login screen shows TrueNAS for a fraction of second before changing the Title to FreeNAS
This issue was observed in 11/24/2017 nightlies since a nightly has not been generated for later days(I checked by going to system>Update)
I also have discussed this with Lola VB and Erin. I think they came up with a solution.
I dont have a screenshot for the moment it shoes TrueNAS(since its for a fraction of second). I have shown this to the developers though.
