So, wouldn't the debian way to do things be to install checkinstall as well, and do a Code: sudo checkinstall instead of Code: make install ?
Makes me feel safer Generating a .deb makes me feel safer. I have in the past installed things with no uninstall script, which made my system unstable, back when I didn't know how to go about manually uninstalling things, and ended up reinstalling my OS as a remedy. Yes, you don't have to, but it seems to me that if you have a package manager, you might as well use it.
In this case the only file that is created by the installation is eaccelerator.so, so there's really no need for a .deb package, but of course that's up to you.
