Neither does the ARCH install media, I run it fine from a USB drive, and it supports every wireless card I throw it on. Just for kicks ill boot arch install media and check the total memory usage, but I doubt it is high at all considering I have put arch on laptops from 2005 with no issues. If that is even a concern, then BriT's idea that unraid should only be run on machines with petabytes of storage arrays would make the additional small amount of memory any concern if we are only talking server class machines. EDIT: if the feature is not used, as in there is no config, it is VERY simple in any linux based system to compile it as a module and either 'modprobe' it as needed, or 'modprobe -r' it to remove it when not needed, thus not taking any additional memory for the 99% of users who don't need it.
And to @BRiT there are other scenarios than a storage server for unraid. The primary one being the separation of the host os from the operational day to day use of the machine (qemu/kvm). Being able to do whatever I want in my Windows machine with almost full hardware capabilities, and then deciding I hate Windows and switching to Arch, without affecting my 10 docker containers that handle backups, pihole, plex, etc.. or doing something stupid in Windows and hosing the OS knowing that I can switch to a backed up version of that same VM or even just the spare backup I keep sitting there on disk.
Also, yes, my laptop does have 3 drives, 32GB of memory, an Intel iGPU + NVIDIA 3070ti and 14 cores (20 threads) which far outrivals most 'server' machines you think unraid is made for.
