Description Andrew G. Morgan 2021-09-05 15:38:26 UTC 
This command

   getcap -r /

generates a gazillion warnings because of things like this:

   Failed to get capabilities of file '/proc/183650/task/183650/net/fib_triestat' (Operation not supported)

we should either silently ignore operation not permitted problems, or skip /proc/ altogether by default.
