I use: * personal laptop * work laptop * work desktop * work remote desktops * a bunch of servers Those machines are on different versions of different distros, and thus have different software available, and when the same package name is available, it's occasionally different versions. Work provides a set of customisations, additionally. Every customisation is yet another dimension in the cartesian product of config space, making installation, upgrades and debugging costlier. I used to think customisation paid off, but I no longer do.
