How to clean system
Коньков Евгений
System have many programs.
Wanna to upgrade to new version of FBSD
Is it possible to clean system from garbage (all programs, files,
header files, except configuration files)
like installing FBSD from CD?
is there cmd?
make clean-system

No, there's no such command. If you are looking for a way to 'deinstall
all ports & packages' though, it may be as easy as:
1. Remove all the currently installed ports:
# rm -fr /usr/local
# mkdir /usr/local && cd /usr/local
# mtree -deU < /etc/mtree/BSD.local.dist
2. Remove all the information about 'installed packages', because you
don't have any of these anymore:
# rm -fr /var/db/pkg/*
3. Optionally, if you are going to reconfigure all your ports from
scratch, remove the saved port configuration options:
# rm -fr /var/db/ports/*

I have tried: pkg_delete -a
but many files are left in /usr/bin /usr/sbin ... (((
also there are files from old 7.2 system, now I have 9.0

Keep in mind that FreeBSD is not Linux. There is the base
system (/usr/bin, /usr/sbin, ...), and there are the
applications installed by ports or packages (/usr/local
subtree). See /usr/src/Makefile's comment section about
how to clean out obsolete parts of the base system.

Packages should never install stuff in /usr/bin and /usr/sbin. Ports
should *only* install files in /usr/local/... There are a few ports that
includes options to override base-system files in /usr but these are the
exception.
If you have been upgrading from source from 7.2 then you should also
have a look at the `/usr/src/UPDATING' file; especially at the help
about the 'make delete-old' targets of the source makefiles.
Most of the cruft left behind from old, obsolete stuff can be deleted by
running
# cd /usr/src
# make delete-old
and following the prompts.

The doc ports install into /usr (granted, not /usr/bin nor /usr/sbin
AFAIK) by default. I would not be at all surprised if a few others
did also.

Deleting /usr/local will also delete /usr/local/etc -- which might be
not what the OP expects given the "except configuration files". I
would still follow the pkg_delete path, along with some other actions:
- if you have fusefs, ntfs-3g, linprocfs, etc in your /etc/fstab --
unmount and comment out temporarily
- if you have third party services in your /etc/rc.conf[.local] --
stop and comment out
- if you have third party modules in /boot/loader.conf -- the same thing
% pkg_delete -adf
% rm -R /usr/local/lib/compat/pkg
% rm -R /var/db/pkg/* # if anything was left there
% rm -R /var/db/ports/* #if you want to clean up your ports' configurations
% rm -R /usr/ports/distfiles/* # not sure if you need it, but I do it
in some cases...
% rm -R /usr/obj
Check /usr/local and /usr/compat to see if you want to remove anything
from there manually. You might want to clean up /usr/local/include,
/usr/compat/linux/var, /usr/compat/linux/usr/local, /usr/local/bin
(?), /usr/local/info ... etc. OTOH, I always preserve
/usr/local/lib/X11/fonts -- I have some custom fonts stored there,
/usr/local/share/stardict -- custom dictionaries I want to survive
across upgrade ... etc.
I also place in /etc/mergemaster.rc something I want to preserve:
/etc/master.passwd
/etc/group
/etc/ppp/ppp.conf
/etc/syslog.conf
/etc/sysctl.conf
/etc/hosts
/etc/namedb/named.conf
Regarding this last item, it might not always be the best way to do,
since sometimes it might be necessary to upgrade some of the default
settings in these files.
Then you can build and install the base system and the ports you need.
Almost all of these steps are easy to automate.
