How To Fix unburden-home-dir: command not found in Ubuntu / Debian / Kali Linux / Raspbian

In Ubuntu unburden-home-dir is provided by unburden-home-dir package.

unburden-home-dir is:

unburden-home-dir allows users to move cache files from browsers, etc. off their home directory, i.e. on a local harddisk or tmpfs and replace them with a symbolic link to the new location (e.g. on /tmp/ or /scratch/) upon login. Optionally the contents of the directories and files can be removed instead of moved.

This is helpful at least in the following cases:

The idea-giving case are big workstation setups where $HOME is on NFS and all those caches put an unnecessary burden (hence the name) on the file server since caching over NFS doesn’t have the best performance and may clog the NFS server, too.

A similar case, but with different purpose is reducing I/O on mobile devices like laptops or netbooks to extend the battery life or reduce the wearing down of CF or SD cards, e.g. in single board computers like the Raspberry Pi or Alix or APU boards: Moving browser caches etc. off the real disk into a tmpfs filesystem reduces the amount of disk I/O which reduces the power consumption of the disk.

Another possible solution for saving non-crucial I/O is using the package eatmydata to ignore a software’s fsync calls.

The other type of use cases for unburden-home-dir is to reduce disk space usage, e.g. on devices with small disk space but a lot of RAM as seen often on boxes with flash disks or early netbooks, e.g. the first EeePC with 4GB disk space and 2GB RAM. In this case you want to move off as many cache files, etc. as possible to some tmpfs filesystem, e.g. /tmp/.

It may also help to reduce the amount of needed backup disk space by keeping those files in places where they don’t get backed up. In that case it’s an alternative to keeping the blacklist in your backup software up-to-date.

For some users it may also be helpful to stay under their quota.

The package also contains an Xsession hook which calls this script on X login for every user. But by default no files or directories are configured to be moved elsewhere, so nothing will happen automatically without configuration.

To fix this problem, we can install more using the command below.

sudo apt-get -y install unburden-home-dir

This command might take some time to finish depending on your machine internet connection.

You can also use apt command to install unburden-home-dir.

sudo apt -y install unburden-home-dir

Or if you have aptitude installed you can use the following command.

sudo aptitude install unburden-home-dir
