NAME

6       debconf-set-selections - insert new values into the debconf database
7

SYNOPSIS

9        debconf-set-selections file
10        debconf-get-selections | ssh newhost debconf-set-selections
11

DESCRIPTION

13       debconf-set-selections can be used to pre-seed the debconf database
14       with answers, or to change answers in the database. Each question will
15       be marked as seen to prevent debconf from asking the question
16       interactively.
17
18       Reads from a file if a filename is given, otherwise from stdin.
19

WARNING

21       Only use this command to seed debconf values for packages that will be
22       or are installed. Otherwise you can end up with values in the database
23       for uninstalled packages that will not go away, or with worse problems
24       involving shared values. It is recommended that this only be used to
25       seed the database if the originating machine has an identical install.
26

DATA FORMAT

28       The data is a series of lines. Lines beginning with a # character are
29       comments. Blank lines are ignored. All other lines set the value of one
30       question, and should contain four values, each separated by one
31       character of whitespace. The first value is the name of the package
32       that owns the question. The second is the name of the question, the
33       third value is the type of this question, and the fourth value (through
34       the end of the line) is the value to use for the answer of the
35       question.
36
37       Alternatively, the third value can be "seen"; then the preseed line
38       only controls whether the question is marked as seen in debconf's
39       database. Note that preseeding a question's value defaults to marking
40       that question as seen, so to override the default value without marking
41       a question seen, you need two lines.
42
43       Lines can be continued to the next line by ending them with a "\"
44       character.

EXAMPLES

47        # Force debconf priority to critical.
48        debconf debconf/priority select critical
49
50        # Override default frontend to readline, but allow user to select.
51        debconf debconf/frontend select readline
52        debconf debconf/frontend seen false
53
