EFI boot order rewrite
by Florian Bauer 22 Feb '23

22 Feb '23

Hello, we are running Rocky Linux on some of our dedicated consumer hardware servers. On the newer servers that boot with efi, the system that is installed with the default properties in the installer writes itself writes itself to the top of the efi boot order each time booting. Since we run all our systems with efi network boot as the first boot option, this would be a problem for the future. Is there any way to prevent this behavior? I have already checked the use of efibootmgr and some of the related grub settings like GRUB_DEFAULT and GRUB_SAVEDEFAULT (which may be unrelated). On Debian, I found an option in debconf that favors nvram writes which prevents this behavior. Does anyone have any ideas about this case? With kind regards Florian

netbooting rocky linux : unable to nfs mount the root file system
by Sandeep Gupta 08 Feb '23

I have posted this question here as well: https://serverfault.com/questions/1122071/netbooting-centos-via-pxe-and-uef…. Essentially, the kernel is able to bootup but fails to mount the nfs root device. I am wondering if rocky linux kernel is able to mount nfs shares? If not, what is the workaround? Would recompile of the kernel with nfs support work? Below, is the grub entry for reference ``` set default="0" set timeout=5 set root=(tftp,192.168.0.185) set prefix=($root)/grub2 menuentry "OS (UEFI PXE)" { linux /vmlinuz-5.14.0-162.6.1.el9_1.aarch64 root=/dev/nfs rw nfsroot=192.168.0.185:/nfs/rpi4_dfd9 rw ip=dhcp rootwait elevator=deadline initrd /initramfs-5.14.0-162.6.1.el9_1.aarch64.img } ``` Thanks -S
