第15章 Installer and image creation

Redesigned the Time & Date spoke in the Installer GUI

The Time and Date spoke of the installer UI is now completely redesigned and does not have a map to select the timezone. For more information, see the installation documentation.

The initial-setup package now has been removed

The initial-setup package has been removed in Red Hat Enterprise Linux 10. As a replacement, use gnome-initial-setup for the graphical user interface.

For new storage devices, the LUKS2 version is used by default

By default, all the new storage devices are now encrypted with the LUKS2 version. No changes are made to the existing devices' LUKS version. You can use the Kickstart method to select different LUKS versions.

Adding additional repositories from GUI is now removed

Previously, when configuring the installation source, you were able to configure the additional repositories for the package installation. Starting RHEL 10, this support has been removed. However, you can use the Kickstart installation method or the inst.addrepo boot option if you want to specify additional repositories.

Anaconda built-in help has been removed

The built-in documentation from spokes and hubs of all Anaconda user interfaces, which was available during Anaconda installation, has been removed. For more information, see the official RHEL documentation.

New users created in Anaconda are administrators by default

Previously, while creating new users from the installer, the Make this user administrator option in graphical installation was deselected. Starting RHEL 10, this option is selected by default. As a result, the newly created users will have administrative privileges by default. You can deselect this option to remove the administrative privileges of the new users, if required.

Removed automatic bug reporting system from Anaconda

The installer no longer supports reporting problems to the Red Hat issue tracking system automatically. You can collect the installation logs and report problems manually, as described in the troubleshooting section.

Capturing screenshots from the Anaconda GUI with a global hot key is removed

Previously, you could capture screenshots of the Anaconda GUI by using a global hot key. This meant that users could extract the screenshots manually from the installation environment for any further usage. This functionality has been removed.

Remote Desktop Protocol (RDP) replaces VNC for graphical remote access

The protocol for graphical remote access has been changed from VNC to remote desktop protocol (RDP). RDP offers a reliable and encrypted connection, overcoming the limitations of VNC, which lacked encryption support and enforced password length restrictions. As part of this change, the following new kernel options have been introduced:

Removed NVDIMM reconfiguration support during the installation process

The support for reconfiguring NVDIMM devices during the Kickstart and GUI installation has been removed in RHEL 10. However, you can still use the NVDIMM devices in the sector mode in the installation program.

Removed inst.nompath, dmraid and nodmraid boot options

The inst.nompath, dmraid and nodmraid boot options have been removed now and are no longer available for use.

The inst.gpt boot option is now deprecated

The inst.gpt boot option is now deprecated and will be removed in the future major RHEL release. To specify a preferred disk label type, use the inst.disklabel boot option. To create GPT or MBR disk labels, specify gpt or mbr option respectively.

The inst.xdriver and inst.usefbx options have been removed

The graphical system for the installation image switched from the Xorg server to a Wayland compositor. As a consequence, the inst.xdriver boot option has been removed. Wayland operates without relying on X drivers, making it incompatible with loading any such drivers. As a result, the inst.xdriver option is no longer applicable.

Logical volume devices in /etc/fstab use UUID in the fs_spec field

After installation, the system writes logical volume (LV) devices in the /etc/fstab file by using UUID in the fs_spec field. This change provides the following benefits:
