Also, even people who chroot daemons are sometimes willing to let them
have access to a few carefully-chosen additional tools. My own
public-facing ftpd, for example, has (rather restricted) access to a
few programs like gzip, so it can do conversions on the fly. I decided
the additional risk was worth the benefit brought.
