Breaking out of the emulation dir

[Edgar Fuß <ef%math.uni-bonn.de@localhost>]

What's the suggested method for breaking out of the emulation directory?
I want <EMULDIR>/opt/tivoli/tsm/client/ba/bin/dsm.opt to be a symlink to
<no-emulation>/usr/pkg/etc/tsm/dsm.opt.
I can achieve this with a considerable amount of ../, but that amount depends
on the value of <EMULDIR>, more precisely, it's expanded value, which happens
to be /usr/pkg/emul/linux32 in the case in question.
I was thinking about a /emul/none -> / symlink.

I'm not sure how the behaviour of the emulation sort-of-chroot is defined
to be if it, for example, looks up /usr/local/foo/bar and e.g. a "real"
/usr/local (or /usr/local/foo) exists, but /usr/local/foo
(or /usr/local/foo/bar) doesn't.
Is this documented anywhere? Has it change since 4.0?
