How does this work with various package managers?

Portage works fine with different PORTAGE_COMPRESS settings.
I guess paludis creates uncompressed man-pages and has three broken links?
And pkgcore?

Is there a reliable/predictable way to create such links?

This is wrong (but works fine with Portage),

<code>

local suffix=$(ecompress --suffix)
dosym foo.1${suffix} /usr/share/man/man1/foo.1${suffix}

</code>

What you really want to do is:

ssuominen@foo /usr/share/man/man1 $ bzcat snice.1.bz2
.so man1/skill.1

This simple one-liner & "fake" manpage will link snice(1) manpage to
skill(1) manpage.

Don't use a symlink, but create a short file with a groff .so request.
See for example the egrep.1 man page, that just contains the one line:

   .so man1/grep.1

wonder if this would be a useful repoman check & recommendation.  dare i grep 
the tree to find all the existing miscreants ...

personally i prefer '.so grep.1' to avoid the redundancy ...
