I know by now most people use 4GB of ram or even 8GB to start. But since the website says minimum 2GB, I tried revitalizing an old Buffalo NAS that runs with 2GB of ram.   unRaid works, but I get some errors with the rootfs getting full and can't update to a newer version either. I keep getting this error every time I try.    inflating: /tmp/unRAIDServer/bzmodules unzip error 0 plugin: run failed: /bin/bash retval: 1   Also this from the Update Assistant plugin.
