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 …
[View More]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

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 …
[View More](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
