Update on the KDE KF5 build boondoggle

[Mark Haney]

I was all prepared to upgrade my F22 KDE laptop to F23 when I got the
kf5-filesystem warning when trying to download the upgrade files.  I did
some digging and found a couple of previous posts (and the bug report)
about the issue, but wasn't able to get a complete, current status of this.

Can someone bring me up to speed on where we are with this?  I've got a
dozen or so similar systems I would like to upgrade but am hesitant to do
so until I get some idea of state of this issue.
