Definitely auto=adding a call to maemo-optify is something that MUD
might do (as Graham already suggested), and I agree it's something
which shouldn't be done at the autobuilder (at least until it becomes
a problem that no-one's using /opt).
However, I'd love to see the output above be:
$ maemo-optify-deb ecoach_1.53beta3_i386.deb
usr/bin/ecoach -> opt/ecoach/bin/ecoach
usr/share/ecoach -> opt/ecoach/share/ecoach
usr/share/icons/hicolor/scalable/hildon/ecoach.png -> \
opt/ecoach/share/icons/hicolor/scalable/hildon/ecoach.png
usr/share/pixmaps/ecoach -> opt/ecoach/share/pixmaps/ecoach
ecoach: optified 4 entries, saving about 546 kB.
In this, I thought about usr/share/ecoach -> opt/ecoach/share, but it
introduces problems and over-complications with .../share/pixmaps and
.../icons.
What do you think Marius?

Indeed. What's the disk space usage of a symlink? ;-)

Absolutely (hence my keenness on it being more FHS compliant by using
the package name).
Cheers,
