The XDG Base Directory Specification (XDGBDS) defines four directories in a users $HOME dir that should be used for so called DotFiles.

These directories (with their default locations) are:

Please refer to the specification for additional directory definitions and further details. Debian does not require that packages conform to the XDGBDS but strongly encourages upstreams to do so. Debian packages should not be patched for conformance to avoid unnecessary deviation from upstream and other distributions.

Tools and libraries

Debian contains several libraries for different languages that help to implement the XDGBDS:

Status of Packages

Debian does not require packages to conform to the XDGBDS and there is not (yet) a coordinated effort to encourage upstreams to do so. But to avoid duplication of effort we can collect upstream bug reports here regarding XDGBDS conformance.

bugs not yet filled/found: ZSH, gimp, ssh, gnupg, mplayer, dbus, libpurple/pidgin,

Proposal: STATE directory

This is a recurring request/complaint (see this or this) on the xdg-freedesktop mailing list to introduce another directory for state information that does not belong in any of the existing categories (see also home-dir.proposal. Examples for this information are:

The above example information is not essential data. However it should still persist on reboots of the system unlike cache data that a user might consider putting in a TMPFS. On the other hand the data is rather volatile and does not make sense to be checked into a VCS. The files are also not the data files that an application works on.

Some questions that might help to distinguish between the different classes:
