Hello Linux Geeksters. As you may know, Profile Sync Daemon is an open source tool used for speeding up the internet browser, by moving the profile in the RAM memory, via tmpfs. It has support for the most important browsers, including: Firefox, Chrome, Chromium, Opera, Midori, Konqueror, Rekonq, QupZilla and many others. The latest version available is Profile Sync Daemon 5.47, which has been recently released.

In this article I will show you how to install Profile Sync Daemon 5.47 on Debian Wheezy, Debian Jessie and Debian Sid.
Because it is available via some third party PPA, installing Profile Sync Daemon 5.47 on Debian is easy. Due to the fact that Debian does not have support for PPAs, you have to manually add the repository to your system, get the key, update the local repository index and install the profile-sync-daemon package. Like this:
$ sudo sh -c 'echo "deb http://ppa.launchpad.net/graysky/utils/ubuntu saucy main" > /etc/apt/sources.list.d/graysky.list'
$ sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys FF7F9516
$ sudo gpg --keyserver wwwkeys.pgp.net --recv-keys C1C5C63BF0E0B4E7
$ sudo gpg --armor --export C1C5C63BF0E0B4E7 | apt-key add -
$ sudo apt-get update
$ sudo apt-get install profile-sync-daemon
Optional, to remove Profile Sync Daemon, do:
$ sudo apt-get remove profile-sync-daemon
Next, make the propper configuration in /etc/psd.conf. Replace username_1 username_2 with the users you want to back up the profiles for:
$ sudo su
# echo 'USERS="username_1 username_2" ' >> /etc/psd.conf
To backup your profiles, via profile-sync-daemon, do:
$ profile-sync-daemon parse
Optional, to remove profile-sync-daemon, do:
$ sudo apt-get remove profile-sync-daemon
