The aim of this program is therefore to + acquire and then send a password to some other program which + will use the password to unlock the encrypted root disk. + + + This program is not meant to be invoked directly, but can be in + order to test it. + + + + + PURPOSE + + The purpose of this is to enable remote and unattended + rebooting of client host computer with an + encrypted root file system. See for details. + + + + + OPTIONS + + + + + + + Specify a different agent directory. The default is + /run/systemd/ask-password as per the + Password + Agents specification. + + + + + + + + + Specify a different helper directory. 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. Note: This + must be a number, not a name. + + + + + + + + + Change real group ID to GROUPID + when running MANDOS_CLIENT. + The default is 65534. Note: This + must be a number, not a name. + + + + + + MANDOS_CLIENT + + + This specifies the file name for + mandos-client8mandos. If the + option is given, any + following options are passed to the MANDOS_CLIENT program.
