# The profile files provided with the firejail distribution include `.local`
|
|
# profile files using relative paths. The way firejail works when it comes to
|
|
# handling includes is by looking target files up in `~/.config/firejail`
|
|
# first, and then trying `SYSCONFDIR`. The latter normally points to
|
|
# `/etc/filejail`, but in the case of nixos points to the nix store. This
|
|
# makes it effectively impossible to place any profile files in
|
|
# `/etc/firejail`.
|
|
#
|
|
# The workaround applied below is by creating a set of `.local` files which
|
|
# only contain respective includes to `/etc/firejail`. This way
|
|
# `~/.config/firejail` still takes precedence, but `/etc/firejail` will also
|
|
# be searched in second order. This replicates the behaviour from
|
|
# non-nixos platforms.
