#25 Drop dependencies for /bin/sh

[Mikael Bouillot]

I installed lMule in a chroot jail, and I had a
couple of problems until I realized the program needs
/bin/sh, /bin/cp and /bin/mv to work properly. I guess
it is using system() to do a couple of file tasks.

Not using system() would allow for better security in
the chroot environment and simpler setup. If it's not
possible, at least documenting these dependecies would
be a good thing.
