Nobody is working on it and the linux base port diverged here since -8
(let's call it a little shift in what to expect from it since Trevor
maintained them).

A chroot will not work as expected:
---snip---
REMOVE_DIRS=            boot dev home initrd root tmp var/log var/run var/tmp \
                        usr/local usr/tmp
REMOVE_FILES=           bin/df bin/su etc/exports etc/group etc/localtime \
                        etc/motd etc/passwd etc/printcap etc/services \
                        etc/protocols
---snip---

We rely on the fallthrough to the FreeBSD files. The same applies to
e.g. fonts.conf in the linux-fontconfig (or linuxfreetype?) port.

For the gtk/X11 port I'm not sure if we already did the fallthrough for
the icons.

Any ideas how to provide a chroot while not losing the fallthrough if
not chrooted (and we try to identify other files/dirs where we want a
fallthrough)?

Bye,
Alexander.
