Since pam_namespace is not used by default, the appropriate package
relationship here would only be a Suggests:, not a Depends: - which means
the dependency would still not be pulled in by default.
Better would be if we had a script that worked with any version of awk.
I'll look into fixing this. Note also that even with gawk installed, by
default this line returns nothing, since there is no 'UMASK' line
uncommented in /etc/login.defs.
This probably works:
mask=$(awk '/^UMASK/{gsub("#.*$", "", $2); print $2; exit}' /etc/login.defs)
mode=$(printf "%o" $((0777 & ~$mask)))
