Runs Daemons with restricted File System Accessftp://ftp.porcupine.org/pub/security/index.html
Chrootuid makes it easy to run a network service at low privilege level and
with restricted file system access. At Eindhoven University we use this program
to run the gopher and www (world-wide web) network daemons in a minimal
environment: the daemons have access only to their own directory tree, and run
under a low-privileged userid. The arrangement greatly reduces the impact of
possible loopholes in daemon software.
