We’ve got the latest gossip on Apple’s brand new filesystem & why you should care! Plus Dan dives deep into the wonderful world of ZFS and FreeBSD jails & shows us how he is putting them to use in his latest server build.
Plus it’s your fantastic feedback, a riotous roundup & so much more!
ZFS, jails, FreeBSD
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.
