Subject: [PATCH] nixos/update-users-groups.pl: chomp hashedPassword
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We don’t want any trailing whitespace, otherwise we mess up the
formating of the shadow file. Some things like readFile may have the
trailing new line.

Fixes #66745
