From the description section of man 5 umask command, it says
For example, the following default ACL is equivalent to a umask of 022:
u::rwx,g::r-x,o::r-x
What's the significance of having another value which is a compliment of UMASK instead of umask itself as an ACL value?

@ctrl-alt-delor why is it confusing that a bitmask is masking bits (turning them off)? I have a strange feeling of déjà-vu -- we already beat this horse to death.
