I use something like the following for copying stuff into chroot. Note:
this works for me, but might not do in certain corner cases.
Glue aside, use ldd to figure out which libraries are needed and copy
those.
This was just a quick hack. Being a shell script, it is also quite
inefficient - mostly due to the fact it starts lots of programs. I might
one day create a Perl implementation, which would be much faster.
Any comments are welcome, as always.
One noteworthy thing is that it attemps to synchronize directories -
notably, it will delete anything from the destination directory not
found in the source directory. One other noteworthy thing is that it
Does not clear old libraries.
