Customize a .deb package
In this case I had to fix some startup links in a Networker Debian package. If I recall correctly it was after I had to use alien to create a .deb package from the vendor's rpm packages.
Package made with alien caused the following errors:
# dpkg -i lgtoclnt_7.5.1-2_amd64.deb Selecting previously deselected package lgtoclnt. (Reading database ... 22181 files and directories currently installed.) Unpacking lgtoclnt (from lgtoclnt_7.5.1-2_amd64.deb) ...

Uncompress with ar:
# ls lgtoclnt_7.5.1-2_amd64.deb # ar vx lgtoclnt_7.5.1-2_amd64.deb x - debian-binary x - control.tar.gz x - data.tar.gz
Uncompress control file:
# tar xzpf control.tar.gz
Now make your changes to pre and post scripts.
Package control.tar.gz
# tar cpf control.tar control md5sums postinst postrm preinst prerm # rm control md5sums postinst postrm preinst prerm
Package the .deb with ar:
# ar -r lgtoclnt_7.5.1-2_amd64.deb debian-binary control.tar.gz data.tar.gz ar: creating lgtoclnt_7.5.1-2_amd64.deb

Although my goal was fix the packaged version, you can also fix startup scripts on Debian and friends with update-rc.d. Example:
root@clnt:/etc/init.d# touch testscript # update-rc.d testscript defaults update-rc.d: warning: /etc/init.d/testscript missing LSB information update-rc.d: see <http://wiki.debian.org/LSBInitScripts> Adding system startup for /etc/init.d/testscript ... /etc/rc0.d/K20testscript -> ../init.d/testscript /etc/rc1.d/K20testscript -> ../init.d/testscript /etc/rc6.d/K20testscript -> ../init.d/testscript /etc/rc2.d/S20testscript -> ../init.d/testscript /etc/rc3.d/S20testscript -> ../init.d/testscript /etc/rc4.d/S20testscript -> ../init.d/testscript /etc/rc5.d/S20testscript -> ../init.d/testscript # update-rc.d -f testscript remove Removing any system startup links for /etc/init.d/testscript ... /etc/rc0.d/K20testscript /etc/rc1.d/K20testscript /etc/rc2.d/S20testscript /etc/rc3.d/S20testscript /etc/rc4.d/S20testscript /etc/rc5.d/S20testscript /etc/rc6.d/K20testscript
