freebsd-update how to update jail?

[bryn1u]

Hey,

I was wondering how I can update a jail with freebsd-update(). ezjail is using binary update/upgrade, so why can't I do that the same way? I don't know how to. Can someone help?

What makes you think you can't? Just make sure the jail's root has been mounted read-write (if that isn't already the case anyway), that the jail has access to the Internet (or to a mirror on your LAN) and run freebsd-update in the usual manner.

Note: if you have several jails sharing a read-only root (as described in the Handbook somewhere), make sure the root is mounted read-write in one of the jails. Running freebsd-update in that particular jail should then result in all those jails being updated at once. Be sure to check whether freebsd-update updates any files that are not shared between jails and copy them manually if necessary.

Also, always update jails before updating the host.

Ah, so it's the normal procedure like on the host. Ok. Thank you for the advice.

It can also be run from the host side using the -b option of freebsd-update(8). That's how ezjail does it.

Thanks for the hint.

In some cases that's probably even easier because one wouldn't need to remount a jail root that's normally only mounted read-only as read-write first.
