NAME
debconf-set-selections - insert new default values into the debconf database
SYNOPSIS
debconf-set-selections file
debconf-get-selections | ssh newhost debconf-set-selections
DESCRIPTION
debconf-set-selections can be used to pre-seed the debconf database with
answers, or to change answers in the database. Each question will be marked
as seen to prevent debconf from asking the question interactively.
Reads from a file if a filename is given, otherwise from stdin.
WARNING
Only use this command to seed debconf values for packages that will be or
are installed. Otherwise you can end up with values in the database for
uninstalled packages that will not go away, or with worse problems
involving shared values. It is recommended that this only be used to seed
the database if the originating machine has an identical install.
DATA FORMAT
The data is a series of lines. Lines beginning with a # character are
comments. Blank lines are ignored. All other lines set the value of one
question, and should contain four values, each separated by one character
of whitespace. The first value is the name of the package that owns the
question. The second is the name of the question, the third value is the
type of this question, and the fourth value (through the end of the line)
is the value to use for the answer of the question.
Alternatively, the third value can be “seen”; then the preseed line only
controls whether the question is marked as seen in debconf's database. Note
that preseeding a question's value defaults to marking that question as
seen, so to override the default value without marking a question seen, you
need two lines.
Lines can be continued to the next line by ending them with a “\”
character.
EXAMPLES
# Force debconf priority to critical.
debconf debconf/priority select critical
# Override default frontend to readline, but allow user to select.
debconf debconf/frontend select readline
debconf debconf/frontend seen false
