Just make another custom script or function that removes
what you do not need. I use following commands to trim both
base system and files installed with packages by scripts called earlier.
Thus, NanoBSD plus 12 installed packages occupied 48Mb only.

cd "$NANO_WORLDDIR"

rm -rf  usr/include/* usr/lib/*.a \
        usr/share/examples/* \
        usr/share/misc/pcvtfonts/* usr/share/syscons/fonts/* \
        usr/share/syscons/keymaps/* usr/share/info/* \
        usr/local/etc/joe/doc/* usr/local/etc/joe/*.dist \
        usr/local/include/* usr/local/info/* usr/local/lib/*.a \
        usr/local/man/* \
        usr/local/share/aclocal/* usr/local/share/doc/* \
        usr/local/share/examples/* usr/local/share/info/* \
        usr/local/share/mc/syntax/* usr/local/share/mc/mc.hlp.*

# prevent Midnight Commander (installed via package) from complaining
touch usr/local/share/mc/syntax/Syntax

# Remove all locale data except of Russian that I use
find usr/local/share/locale -maxdepth 1 | fgrep -v ru | xargs rm -rf

# replace binary /usr/sbin/nologin with small shell script
# that runs under 'sh -p' and says 'This account is currently not available'
ln -f -s /usr/local/nologin usr/sbin/nologin

# remove largest binaries I never use
cd usr/bin
rm -f openssl vi ex view nvi nex nview make makeinfo info vacation
cd ../sbin
rm -f iasl acpidb hostapd amd wpa_supplicant
# EOF
