[trelliscoded]

A product I worked on got real popular, so scaling up the support department became a real pain since the devs were running all kinds of different distros and so we had CI and package support for Arch, Debian, Ubuntu, CentOS... except that all of those come in a bunch of different variants and customers expected the product to run on them. At one point more than 90% of the tickets were dealing with distribution-specific weirdness. There was an epic internal wiki page that must have weighted in at a couple megabytes of raw text that was an encyclopedia of run-time linker caveats for hundreds of distributions, complete with troubleshooting flowcharts and links to our internal test farm to get one-click access to a VM reproducing the scenario described. I still wish I had that, it would have been so handy for some of the Rust and MIPS porting I'm doing now.

We couldn't containerize it (it's a client for a security monitor), we couldn't ship it as a VM, so eventually we all agreed to ditch everything except RHEL and everyone else would be unsupported (we grandfathered all the existing ones in, and it took a year and a half before everything worked.).
