Might seem a little far-fetched, but i’m going to go out on a limb here and say that the community that basically worships conspicuous consumption of electronics with complete disregard for e-waste and electrical consumption in support of being a better gamer, a consumer identity fabricated by marketing companies, and have thus turned it into an implicit contest might not be interested in practicality, liberty, nor freely available goods unless they’re the most visually appealing
Boot into a livedisk and transfer some space from a bigger partition to var. I had the same problem tbh, and iirc I just chose to go with /home and everything else as 2 separate partitions, didn’t see the value of having /, /usr, and /var as 3 different ones (plus fstab has caused me some issues whenever one of my disks is slower to come online than the primary, so I just figure the less partitions the better)
