NAME

appjail-update — Update a thick jail or a release

SYNOPSIS

DESCRIPTION

The appjail update is a utility to fetch and install updates to a jail or a release.

The options are as follows:

jail [-bfKk] [-j jobs] jail

Update jail.

You can only update a thick jail, except when it comes from an empty release.

This subcommand updates a thick jail using freebsd-update(8) (binary updates) or using the FreeBSD source tree (source updates); However, it depends entirely on how this jail was created. For thin jails, it is not possible to use this subcommand, but there are at least two methods: the first method uses appjail-etcupdate(8) after updating the release that uses the thin jail and the second method is to separate the data that needs to be persisted from data that is considered ephemeral, so you can destroy and recreate a jail, but preserving the non-ephemeral data.

Note that when the jail comes from a build from the FreeBSD source tree, the release is linked indirectly. To detect that the jail comes from a build from the FreeBSD source tree, to obtain the kernel configuration file, architecture, version and other parameters this subcommand uses the release directory, since those parameters are stored there. This is important if you want to export the jail and the release on another system.

-b

Build the world and, if the kernel was compiled successfully when building the release (and if -K is not specified) or -k is specified, the kernel.

-f

Force freebsd-update(8) fetch to proceed in the case of an unfinished upgrade. Ignored when the jail was created using a build from the FreeBSD source tree.

-K

By default, this subcommand detects whether a kernel has been compiled successfully when the release is created, so it will proceed to install the kernel again and, if -b is specified, it will build the kernel again. This option disables this behavior.

-k

Build and install the kernel even if it is not necessary, that is, when it was not compiled correctly or at all when creating the release.

-j jobs

Number of jobs. If this option is not set, the number of jobs specified by the JOBS parameter is used.

release [-f] [-a arch] [-v version] [release]

Update release.

A release cannot be updated if it was created using a build from the FreeBSD source tree or if it is an empty release. On the one hand, an empty release is assumed to be the user, you, the only person who knows how to update it, and on the other hand, to update a release that was created using a build from the FreeBSD source tree, appjail-fetch(1) should be used and, if your workflow requires it, you should also use appjail-etcupdate(1) and appjail-deleteOld(1).

-f

Force freebsd-update(8) fetch to proceed in the case of an unfinished upgrade.

-a arch

Update release with the given architecture.

-v version

Update release with the given version.

EXIT STATUS

The appjail update utility exits 0 on success, and >0 if an error occurs.
