Subject: bugfix: place guy files under network directories

guy files were getting written in the correct directory but were getting
updated on the parent directory (/users)

this moves the "update guy file" logic to its own function so this sort
of thing doesn't happen again

writing blocks to disk got moved to its own function as well
