Subject: Add --prompt option to ask-for-password client command
X-Git-Tag: 0.6.0~182
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=dbe8e595d399bf7b39e7634032812794cc6b583d;p=thirdparty%2Fplymouth.git

Add --prompt option to ask-for-password client command

We want to be able to ask the user a question instead
of assuming they know what question to answer. This
will be important if /opt and /home get encrypted with
different passwords.
