Sure, it's perfectly sensible to keep both if you need both, but why on
earth does that require manually moving libraries around (which you
should almost never do)? libfoo_bar.so.1* would be in a libfoo-bar1
package, while libfoo_bar.so.2* would be in a libfoo-bar2 package, and
the two should be coinstallable. No reason to move files around by
