I've used live-build tools in order to build my own live-usb image with custom logo, custom bootmenu and custom packages (i need gparted, tcpdump and hping in addition to basic set). The custom logo and bootmenu are working perfectly

- purged all
- added --interactive shell arg to lb config
- dowloaded required debs and its depencies
- after got chrooted shell, copied all debs to chrooted location and installed via dpkg -i *.deb
Both ways gave me no success. Desired packages are missing in live system. Can i get any help?
