Indeed it did. Shorter: env LD_LIBRARY_PATH='/usr/local/lib:$LD_LIBRARY_PATH' /usr/local/bin/jq --version > Chrooting to / works because rc(8) runs ldconfig(8) to add > /usr/local/lib and /usr/X11R6/lib if they're present. > > You can copy all the libraries into /var/www/usr/lib, you can set > LD_LIBRARY_PATH=/usr/local/lib:/usr/, or you can run ldconfig in the > chroot. > > Read ld.so(1) and ldconfig(8)for more details. Yes, setting `ldconfig -n /usr/local/lib` is a more sticky option. The `env` approach seems best when just one `jq` command, whereas the `ldconfig` approach seems better when there is more than one `jq` command... Thanks! K.
