How to update EFI partition after kernel upgrade?

Hi all,

after a kernel upgrade my modules are gone, and of course I need to reboot to
be able to load the new modules. The thing is, before I reboot I need to copy my
new kernel and initramfs to the EFI partition, which requires me loading the vfat module,
which is now gone...

As far as I can tell, I am going to need a secondary OS (or live cd) to solve this....,
I think this is a design bug... any ideas?

Luckily I had tried to recompile the kernel a week ago and had a copy of the modules in another directory.

Otherwise I would be in trouble, this should be solved.

Add the efi partition to fstab, so it gets mounted at boot time. If your bootloader supports non-.efi named kernels (rEFInd does), you could simply bind the directory you put the kernels into onto /boot at boot time, so that you don't need to manually copy the kernel + images each time you update it.

For example, I have the following in my fstab:

UUID=DA2E-688C                            /mnt/efi                                  vfat defaults                                    0 2
/mnt/efi/EFI/arch                         /boot                                     none bind                                        0 0

Thank you, it is a solution which I will implement, though maybe a warning of some sort should be made so this doesnt happen to unwary users.
