Profile-sync-daemon (psd) is a tiny pseudo-daemon designed to manage browser profile/profiles in tmpfs and to periodically sync back to the physical disc (HDD/SSD). This is accomplished by an innovative use of rsync to maintain synchronization between a tmpfs copy and media-bound backup of the browser profile/profiles. Additionally, psd features several crash recovery features.
The psd-overlay-helper script is used internally to enable the usage of the overlay file system. It should not be called by the user directly.
