Started to try overlay fs w/one fs, but decided on another, so umounted the first -- hadn't done any changes. Then tried a different lower dir (/home) and tried to mount into new dir /home2. Got: mount: /home2: mount(2) system call failed: Stale file handle any idea why? I cleared out contents of workdir (two empty dirs) but still didn't work again. running a Vanilla-ish self-made kernel version 5.9.2... don't know what other info I should provide...oh well...
