SYNOPSIS
pam_umask.so [debug] [silent] [usergroups] [umask=mask]
DESCRIPTION
pam_umask is a PAM module to set the file mode creation mask of the
current environment. The umask affects the default permissions assigned
to newly created files.
The PAM module tries to get the umask value from the following places
in the following order:
o umask= argument
o umask= entry of the users GECOS field
o pri= entry of the users GECOS field
o ulimit= entry of the users GECOS field
o UMASK= entry from /etc/default/login
o UMASK entry from /etc/login.defs

- If the user is not root, and the user ID is equal to the group ID,
and the username is the same as primary group name, the umask group
bits are set to be the same as owner bits (examples: 022 -> 002,
077 -> 007). - umask=mask
- Sets the calling process's file mode creation mask (umask) to mask & 0777. The value is interpreted as Octal.
