Automate package installation in Debian [SOLVED]?

Question

linux

Hello cheaters!
Set up a PXE preseed Debian installation. Everything is working well.
Specified additional packages to be installed in the di pkgsel/include string option (console-cyrillic, localepurge, etc.).
Everything is ok, but the above packages want answers to their questions.
Installation needs to be fully automatic.
Where to dig?

Answer 1

debconf-get-selections | grep XXX
and add lines:
XXX XXX/some_option option_type option_value

Answer 2

As far as I remember, there were some flags that forced the default to answer all questions. But unfortunately I don't know anything about PXE preseed and may be answering some other question.
