Title:
AppArmor support for the XDG Base Directory spec is incomplete
Status in apparmor package in Ubuntu:
New
Bug description:
Based on the version of apparmor in trusty-updates:
Various profiles grant permissions for files in @{HOME}/.cache/. This
is only sufficient as long as one hasn't set the environment variable
XDG_CACHE_HOME to point somewhere else. (Use case: store caches
locally when home directories are on a remote fileserver.)
I'd suggest defining a new tunable
@{XDG_CACHE_HOME}=@{HOME}/.cache/
which local administrators could augment as needed (e.g.,
@{XDG_CACHE_HOME}+=/var/cache/xdg/*/
or whatever the local convention may be).
Similar treatment may be needed for the other environment variables mentioned in the XDG basedir spec:
XDG_CONFIG_HOME for @{HOME}/.config
XDG_DATA_HOME for @{HOME}/.local/share (and/or @{HOME}/.local ?)
