Any packages installed on image mode hosts are temporary and disappear after a reboot.
Because of this, installing packages is generally discouraged, except for debugging purposes or, in some cases, when applying critical security patches.

In the New UI of the *All Hosts* page, you can display the *Type* column, which includes a mode indicator.
This column is disabled by default, so enabling it views mode information.

= Viewing booted container images
These actions streamline the management of image mode hosts, providing flexibility and control over host operations through {Project}.

.Prerequisites
* *Pull-Mode Remote Execution*: For pull-mode remote execution users, the `foreman_ygg_worker` package must be included in the image mode host's container image.

.Procedure
. Navigate to *Content* > *Booted Container Images* to view all images used by image mode hosts.
This page displays the spread of digests under specific image paths.
More digests under an image path indicate greater drift in the host ecosystem, ideally minimized by ensuring all hosts run the most up-to-date image version.
. Click the host count to navigate to the *All Hosts* page, which identifies the hosts associated with each specific image and displays the number of hosts using each digest.
. Select a host and on the *Details* tab, use the image mode *Details* card to see the current `bootc` status.
. Click the link to the *Bootc Action - Script Default* remote execution job in this card to perform a Bootc action on the host.
For pull-mode remote execution users, the `foreman_ygg_worker` package must be included in the image mode host's container image.

.CLI procedure
* Run the `hammer host bootc images` command.
