FreeBSD VPS
After nine months testing we are now offering FreeBSD VPS Hosting on the SAVVIS network.
Among the most difficulties was developing a way for in-Jail quota support (as far as I know we are the first to offer this on FreeBSD) without UID/GID conflicts with other jails. This was accomplished by creating a memory disk device (see man 8 mdconfig) for each jail and mounting them as partitions. See falconhosting.net
