Unburden Your Home Directory
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
/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
$HOMEis 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: 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 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, especially the EeePC, where configurations with 4GB disk space and 2GB RAM are not seldom. In this case you want to move off as many cache files, etc. as possible to some tmpfs filesystem, e.g.
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.
Another pragmatic use case may be to stay — as an user — within a given disk quota. :-)
