This is more of a FYI in case anyone else has this problem.
I needed to update my VMware application to the VMware-player-15.5.2-15785246 version. When I tried, the installer failed. It turned out it does not like temp and tmp pointing at the ramdisk. Probably doesn't like it pointing anywhere other than the usual spot. After I relocated tmp/temp back and rebooted, I could install the latest VMware.
I doubt this is a problem with the ramdisk, but I thought I would mention it.
