That should have been UMask, not Umask. It could be that Umask is supported.
It is UMask at

You are correct. With long options, it is written as
pacman --sync --refresh --downloadonly --sysupgrade .

pacman -Sywu is not safe. But pacman -Syu is safe. Quoting the wiki, the
rational is that pacman -Sywu
will update the pacman sync database without installing the newer packages.
What I fail to see is why pacman -Sywu, followed by pacman -Su,
1. Will update the pacman sync database without installing the newer packages.
2. Will not update the pacman sync database while installing the
packages it has prevoiusly downloaded.

That is, my understanding is that checkupdates -d is equivalent to
pacman -Sywu && pacman -Su . I haven't read checkupdates manual page. It
could be that other then a safe upgrade it does additional work.
