your boy here already confirmed the recommendation is for 1gb per tb for optimal performance as a general rule of thumb, in that you can use less if you dont care it wont be as fast as it could be
like a true mod make a counter point and then claim the argument is over
bruh you know what i mean. if you boot an install media for say fedora, ubuntu, slackware, mint, debian, arch etc how many will as shipped support zfs as root as /boot etc? is basically none if it was natively supported in the kernel would probably be in 95% of distros within 1 year
which would solve the problem sgt mentioned n the op, meaning he could have just stayed on fedora if he wanted
for recommendation am saying yes i consider that bloat when its suggested a more sophisticated version of a usb external drive have more ram then a users main system, possibly more then would be recommended for say a 4k video editing/3d modeling workstation
i mean if you’re linus media group and have multiple people pulling large files at the same time/lots of video coming in, going out to offsite backups etc sure a more robust higher spec system can definitely be justified, but if were talking a smol box in the back of a closet with 6 drives only one person ever uses and thats just to put shit on, pull it back off once in a forever should work fine with like 4gb of ram
not saying it doesnt do a bunch of cool stuff with those resources assuming one has a use for those features, but it also uses a bunch of resources to do those things
