Hi,
Actually, it's not --vendor="", it's
--vendor="<vendor_id>", with the
explanation of vendor_id just below the examples:
* If upstream uses <vendor_id>, leave it intact, otherwise use
fedora as <vendor_id>.
* It is important that vendor_id stay constant for the life of a
package.
This is mostly for the sake of menu-editing (which bases off of
.desktop file/path names).
Actually,no one remembers why --vendor was added in the first place.
It's a bad idea, and I made it optional a few desktop-file-utils
releases ago.
One reason it's a bad idea is because it makes our desktop files have
a different name than the upstream desktop files. Any code that needs
the name of the desktop file needs to be patched to use our name.
It's just broken.
I would remove --vendor for new rawhide packages completely. If
desktop-file-install is too old to not have vendor at all, then
--vendor "" or --vendor the-name-of-the-file-without-.desktop is
right.
