I would tend to do the opposite. If I had tons of GPUs I'd be more likely to use a mining distro with dedicated
mining rigs centrally managed. As it is now most of my "rigs" are actually multi purpose PCs so I need a full distro.
I tend to see mining distros as targetted at people who just want a specialist mining OS and don't necessarilly
want it to be Linux, but that's the only choice.
But with this use, it is inconvenient to manage mining farms when changing miners or coins. Special Linux systems for miners, such as Hive OS, allow users who do not understand Linux to manage farms.
I do not understand what you will do when the mining farms freeze or shut down. I think this is not very convenient for all tasks.
A "farm" is the same as "tons of GPUs" and requires more work to manage so I think we're saying the same thing.
I don't have a farm so I don't need the management included in a mining OS. And my mining rigs are multi-purpose
so I can't use a specialist mining OS.
