This has been discussed a few times.
What about letting packages provide a feature or capability and then other
packages could depend on that feature/capability instead of a specific
One idea would be for mailwrapper: it needs a sendmail. Then postfix,
exim, sendmail could all say they PROVIDE a sendmail.
Debian and some other package systems provide this.
It could also be used if needing an lpr.
I was thinking about this again this week, because I was wondering if it
would be possible to plug-and-play different X11 library implementations
-- without having to rebuild nor reinstall the packages using X. (I am
moving from XFree86 to Xorg.)
Any comments would be appreciated.
