JLinux and EFI boot
New JLinux installations will from 2023-04-01 be installed in EFI mode instead of the traditional BIOS mode.
Existing installations will not be changed automatically, and there is no need to manually change to EFI boot as it adds no extra benefits for existing systems.
The main difference with EFI installations are:
- Disk partition table is GPT
- Disk partition 1 is no longer the root partition, but the EFI boot partition. Partition 2 is the root partition.
- The EFI boot partition is mounted at /boot/efi containing only the EFI boot image.
- New virtual servers on JCloud JVM platform will boot using EFI only.
GRUB behvaiour change
For systems running under EFI, GRUB updates will automatically update the EFI boot image if the partition is mounted at /boot/efi.
JLinux CD image
The JLinux CD image supports both BIOS and EFI boot
