Run commands in restricted environments
Chrootuid makes it easy to run a network service at low privilege level and with restricted file system access. The daemons have access only to their own directory tree, and run under a low-privileged userid. . In the past it has been used to run the gopher and www (world-wide web) network. It can be used nowadays also for proxy servers. The arrangement greatly reduces the impact of possible loopholes in network software.
