As this is a general problem we should move it out of this thread.
I also think this should have been discussed months ago.

The brackets are no problem.
But -mindepth and -delete are not in the specs:

| The -mindepth and -maxdepth options are GNU extensions that should be
| avoided if possible.                             (from devmanual.g.o)
Well, even the portage ebuild uses -mindepth. So should I replace it?

| The `-delete' action was introduced by the BSD family of operating
| systems                                         (from `info find`)
and is also used several times in the tree.

I guess you mean the default expression?

dosed defaults to "s:${D}::g"
$D is supposed to end with a trailing slash.
-> is the path still absolute?

Strange at least.


BTW: After I looked up the devmanual part about "find" above, I wonder:
| find "${S}" -type f | while read f ; do
| [...]
| for f in $(find "${S}" -type f) ; do
| [...]
| Warning
| In both cases, files with weird characters or spaces in their names may
| cause serious problems. 

Is there still a problem in the snippet above and is the following better
(if we assume that packages contain files with sane names)?

pushd "${D}" > /dev/null
for f in $(find . -type f -not -name '*.so' ) ; do
    if file "${f}" | grep -q -i " text" ; then
        sed -i -e "s:${D}:/:g" "${f}" || die
    fi
done
popd > /dev/null

Maybe i need some coffee.
