profile-sync-daemon on Fedora 24

Background

PSD is designed to manage browser profile(s) in tmpfs and to periodically sync back to the physical disc, thereby reducing writes to SSDs. This is useful where there is ample spare RAM on the system.

Installing profile-sync-daemon

profile-sync-daemon was not available in Fedora repositories at the time. To build and install it
