UEFI                              

Prior to installing openSUSE on a system that boots using UEFI (Unified
Extensible Firmware Interface), you are urgently advised to check for any
firmware updates the hardware vendor recommends and, if available, to install
such an update. A pre-installed Windows 8 is a strong indication that your
system boots using UEFI.

Background: Some UEFI firmware has bugs that cause it to break if too much data
gets written to the UEFI storage area. Nobody really knows how much "too much"
is, though. openSUSE minimizes the risk by not writing more than the bare
minimum required to boot the OS. The minimum means telling the UEFI firmware
about the location of the openSUSE boot loader. Upstream Linux Kernel features
that use the UEFI storage area for storing boot and crash information (pstore)
have been disabled by default. Nevertheless, it is recommended to install any
firmware updates the hardware vendor recommends.

UEFI, GPT ?? MS-DOS ????

Together with the EFI/UEFI specification, a new style of partitioning arrived:
GPT (GUID Partition Table). This new schema uses globally unique identifiers
(128-bit values displayed in 32 hexadecimal digits) to identify devices and
partition types.

Additionally, the UEFI specification also allows legacy MBR (MS-DOS)
partitions. The Linux boot loaders (ELILO or GRUB2) try to automatically
generate a GUID for those legacy partitions, and write them to the firmware.
Such a GUID can change frequently, causing a rewrite in the firmware. A rewrite
consist of two different operation: removing the old entry and creating a new
entry that replaces the first one.

Secure Boot ????????

???????? UEFI ????????????????????????????

The new version of the shim loader allows more machines to boot with Secure
Boot enabled than with openSUSE 13.1. Nevertheless, in case of trouble, first
update the BIOS of your machine to the latest version. If the BIOS update does
not help, report the model of your machine to the wiki (http://en.opensuse.org/
openSUSE:UEFI). Then we can track it for the next release.

AppArmor ??????????

AppArmor is enabled by default. This means more security, but might prevent
services from working if you run them in unexpected ways. If you encounter
strange permission problems, try to switch the AppArmor profile for the
affected service to complain mode with:

aa-complain /usr/bin/$your_service

??????????????????????????????????????????????????????

Even if it helps, report it as a bug! We want to fix AppArmor profiles to also
cover corner cases.
