Hi, Im using distrobox for my user space and also for my gamerig (because the host run alpine and I need glib) and I like my games files to be separate from my $HOME, I can change the container $HOME but it is not helping if I have on the host XDG_*_HOME setup. Also Im using distrobox to test apps and build them and its just clutter my home.

It could be solve by adding a env var (for the host) like DBX_HOST_ENV={true,false} and then check it in distrobox-enter.

Im thinking this solution would not work because you need to check that for if I export a program to the host e.g lutris.

I just got into distrobox today, going to use it for LibreOffice bug triaging as bleeding edge distros can't run old versions. I guess implementing this request would allow me to skip having to say unset XDG_DATA_DIRS before I can run gtk3 apps? For now I added it to the .bash_profile of my custom home dir.

Anyone know how to add this feature? Because my solution isnt working, because you 100% need it for just some boxes and not for all.

enter: better control over copied host envvars
977fab6 
Currently, all host environment variables are copied into the container,
except for a hardcoded few that are ignored:
https://github.com/89luca89/distrobox/blob/3b9f0e8d3d8bd102e1636a22afffafe00777d30b/distrobox-enter#L434

This is not always the desired behavior, particularly on host distros
like NixOS or Guix that break from the FHS and need to set a lot of
environment variables to work around the resulting issues:
89luca89#1516

Therefore, provide a --no-envvars option to disable the default copying
of environment variables, and an --additional-envvars option to copy
specific ones.

It was suggested to use `env -u distrobox` in order to unset specific
environment variables:
89luca89#656
However, there are usually too many copied environment variables to
unset them all individually.
`env -i distrobox` will unset environment variables, but that includes
PATH and other things needed for distrobox to execute correctly on the
host.
