Apple’s New File System: Who Cares?

• Apple’s Hierarchical File System

• Apple File System

ZFS, jails, FreeBSD

• FreeBSD Jails

• Origins of FreeBSD Jail and why imperfect virtualization is good

• Jails are like little virtual machines (jails) running on a bigger machine (the jail host)

• From the jail host (often just referred to as the host), you can see into the jails, see everything that’s running, monitor, etc.

• Stuff in the jail cannot see outside the jail and have no interactions with the host

• You can configure the host so that the jail can access stuff on the host (e.g. a tape drive) but that requires explicit action by the sysadmin.

• Simplified concept of a FreeBSD Jail: create a directory, install FreeBSD in there, chroot, done.
