Well, /etc/skel/.ssh/authorized_keys is very convenient. On servers where
PasswordAuthentication is turned off (e.g. on all servers I care for),
~user/.ssh/authorized_keys is changed at least once (unless
AuthorizedKeysFile is also customized). When ~user/.ssh/authorized_keys
is created by useradd, it allows to use tab completion and makes sysadmins
happy. ;)
