In ~/.bash_profile, I have umask=002, since I want directories
(files) to have the permission 755 (644).
Until Fedora 25, this worked perfectly.
Now, in Fedora 26, directories (files) are created with the
permission 775 (664).
When I run umask, it returns 0002.
For some reason, my setting in .bash_profile is no longer being
honoured in Fedora 26! Why?
