bootc-upgrade - Man Page

bootc upgrade [--quiet] [--check] [--apply] [-h|--help]

Download and queue an updated container image to apply.

This does not affect the running system; updates operate in an "A/B" style by default.

A queued update is visible as `staged` in `bootc status`.

Currently by default, the update will be applied at shutdown time via `ostree-finalize-staged.service`. There is also an explicit `bootc upgrade --apply` verb which will automatically take action (rebooting) if the system has changed.

However, in the future this is likely to change such that reboots outside of a `bootc upgrade --apply` do *not* automatically apply the update in addition.

--quiet

Don't display progress

--check

Check if an update is available without applying it.

This only downloads an updated manifest and image configuration (i.e. typically kilobyte-sized metadata) as opposed to the image layers.

--apply

Restart or reboot into the new target image.

Currently, this option always reboots.  In the future this command will detect the case where no kernel changes are queued, and perform a userspace-only restart.

-h,  --help

Print help (see a summary with '-h')
