The default is + /lib/mandos/plugin-helpers, which + will exist in the initial RAM disk + environment. (This will simply be passed to the + MANDOS_CLIENT program via the + MANDOSPLUGINHELPERDIR environment variable. + See + mandos-client8mandos.) + + + + + + + + + Change real user ID to USERID + when running MANDOS_CLIENT. + The default is 65534.
