Also, make yourself available (in a limited capacity that works to your spoons and availability) for ongoing tech support. One of the scariest things with switching to Linux is 'what if I need help?' - folks will need to be guided gently towards knowing where to look online for answers specific to their distro etc.; there are *so many* forums, places like Reddit are notoriously shit and gate-keepy, it's not always an easy process finding out 'I'm seeing X error, what do I do'.

I was incredibly lucky when I switched to Linux that I was living with @jaco at the time who is more knowledgeable than I am; he's no expert, but he had a few years more experience of Linux than me, and also is a coder so is kinda generally more accustomed to things like command lines (not that you need command line stuff as much these days). He still helps me remotely with Linux issues, just things like 'open the console and enter this command then see if that works'.

If you're going to run something like this, maybe also source a few other local people who can help with different distros and desktop environments, who are also willing to lend tech support, so you've got people for all the common ones like Gnome, KDE, Manjaro, Mint, Debian, whatever.
