# 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.
#
# See https://github.com/netblue30/firejail/blob/e4cb6b42743ad18bd11d07fd32b51e8576239318/src/firejail/profile.c#L68-L83
