SECURITY NOTICE
If you use the --login-program and --login-options options, be
aware that a malicious user may try to enter lognames with
embedded options, which then get passed to the used login
program. Agetty does check for a leading "-" and makes sure the
logname gets passed as one parameter (so embedded spaces will not
create yet another parameter), but depending on how the login
binary parses the command line that might not be sufficient.
Check that the used login program cannot be abused this way.
Some programs use "--" to indicate that the rest of the command
line should not be interpreted as options. Use this feature if
available by passing "--" before the username gets passed by \u.
