However, it supports hosting other Linux guest OSes under LXC control, making it an attractive hosting solution as well. Uses Busybox and musl. ClearOS: Active: Red Hat Enterprise Linux derivative: x86, x86-64: GPL and others: Free or paid registration: Router and firewall for SMBs with network, gateway and server modules accessed through ...
