I just realized that as part of the upgrade of grommit to Solaris 10, my usage statistics were no longer being updated. (I use Webalizer; you can see the report that it generates here.) I logged in to grommit, and saw at once that my cron job wasn’t running. This was actually a good thing, since the Webalizer binaries were all compiled for Linux!
The natural thing would have been to grab the source and rebuild Webalizer, but when I arrived at the download page I noticed that there was a prebuilt distribution for Solaris 2.8 on x86. The Solaris engineers work hard to maintain 100% binary compatibility, and Brad writes really clean code, so it should just work, right?
And it did. Kudos all round.
