The baselayout ebuild we are using has a multitude of bugs and should be completely rewritten.

It currently creates a /usr/sbin/bin -> bin symlink, which is a failure related to it trying to create a symlink from /usr/sbin -> bin (which is also wrong.)

ffs also has the following hacks to ensure baselayout doesn't screw things up further:

install -m 0755 -d $ROOT/usr/bin
install -m 0755 -d $ROOT/bin
# without this, /sbin ends up being a symlink to /usr/sbin?!
install -m 0755 -d $ROOT/sbin
# without this, /usr/sbin ends up being a link to bin?!
install -m 0755 -d $ROOT/usr/sbin
# also fix a lib issue -- did I miss some steps from metro?
install -m 0755 -d $ROOT/lib64
ln -sf lib64 $ROOT/lib
install -m 0755 -d $ROOT/usr/lib
ln -sf lib $ROOT/usr/lib64

Metro has similar workarounds.

Currently, baselayout uses a separate Makefile which is included in an upstream gentoo tarball from: https://gitweb.gentoo.org/proj/${PN}.git/snapshot/baselayout-2.6.tar.bz2

This all needs to be replaced.

Also – baselayout currently hard-codes the Funtoo release as 1.4.
