I did search of umask in bash_history log or any system wide logs, didn't see
any manual changes of umask, and checking its value now, is still the default
0022
as I understand, umask applies for new files creation only, while my home
directory existed for a long time, since the system installation
for those Linux servers, fortunately I still have other accounts can login to
check, and run sudo chmod g-w /home/user; it looks like only the most often
used account is affected; many other user accounts under /home have no impact.
