You're falling victim to the greedy match. Have a go with this:

Code:
echo "/*<tagz>*/${tagz}.unix some random text and /*<tag1>*/${tag}.unix" | sed -E 's!\*<([^>]*)>[^.]*\.!*<\1>*/${\1}.!g'

Only tried it on your sample and one other contrived example, so it might not be perfect. I also prefer using -E to avoid escaping parens which just make it messy. If you are using a BSD based sed it'll be a different (-r or -R, I cannot remember and my BSD box isn't up right now).

HISTORY

       The GNU shtool subst command was originally written by Ralf S.  Engelschall <rse@engelschall.com> in 2001 for GNU shtool.  It was prompted
       by the need to have a uniform and convenient patching frontend to sed(1) operations in the OpenPKG package specifications.

SEE ALSO

       shtool(1), sed(1).
