Should you wish to add a certain kernel and initrd image to the list of Should you wish to add a certain kernel and initrd image to the list of
bootable kernels you need to: bootable kernel use `pve-efiboot-tool kernel add`.
* create a directory on the ESP (e.g. `/EFI/personalkernel`) For example run the following to add the kernel with ABI version `5.0.15-1-pve`
* copy the kernel and initrd image to that directory to the list of kernels to keep installed and synced to all ESPs:
* create a entry for this kernel in `/loader/entries/*.conf`
NOTE: do not use `/EFI/proxmox` as directory since all entries there can be
removed by `/etc/kernel/postinst.d/zz-pve-efiboot`
Example (keeping kernel 5.0.15-1-pve and copying to an ESP mounted on
`/mnt/esp`):
---- ----
mkdir /mnt/esp/EFI/preferred-kernel pve-efiboot-tool kernel add 5.0.15-1-pve
cp /boot/initrd.img-5.0.15-1-pve /boot/vmlinuz-5.0.15-1-pve /mnt/esp/EFI/preferred-kernel
echo -n "title Preferred Kernel
version 5.0.15-1-pve
linux /mnt/esp/EFI/preferred-kernel/vmlinuz-5.0.15-1-pve
initrd /mnt/esp/EFI/preferred-kernel/initrd.img-5.0.15-1-pve

cat /etc/kernel/cmdline >> /mnt/esp/loader/entries/preferred.conf
---- ----
`pve-efiboot-tool kernel list` will list all kernel versions currently selected
for booting:
----
# pve-efiboot-tool kernel list
Manually selected kernels:
5.0.15-1-pve
Automatically selected kernels:
5.0.12-1-pve
4.15.18-18-pve
----
Run `pve-efiboot-tool remove` to remove a kernel from the list of manually
selected kernels, for example:
----
pve-efiboot-tool kernel remove 5.0.15-1-pve
