Yes, it has been discussed multiple times, it would be very useful and it's already on the TODO list. Trouble is, adding that information on the list of machines while allowing edition through the admin web interface is a bit involved: it needs Django model changes. Currently I'm the only one with enough expertise on the Django code [1], and there are other priorities (-ENOTIME). I believe at this point we could simply postpone this for the upcoming cfarm.net static website, which should contain a documentation section and will be easier to edit. Zach has been working on this new website but it's not ready yet. Baptiste [1] https://framagit.org/compile-farm/gccfarm
