# psd-overlay-helper(1)

Script to use overlay file system for profile-sync-daemon.

## NAME

**psd-overlay-helper** - Script to use overlay file system for profile-sync-daemon.

## DESCRIPTION

**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.**
