We’re actually having more dire (and possibly related) issues with this in Fedora. I’ve had reports about the SELinux context and in some cases the contents of the file being clobbered, which winds up breaking everything. One example of this is RH#1596753. Another is RH#1612430.
I’m not sure what’s going on here, as this isn’t supposed to be happening at all. But it’s causing problems.
