I use genkernel to build my kernels and initramfsen. Most of my
machines don’t support EFI, so my /boot contains a bunch of
{initramfs,kernel,System.map}-$KV files plus the
{initramfs,kernel,System.map}.old symlinks. My GRUB2 grub.cfg points at
the symlinks. Once in a while (usually when I get disk full errors on
the dedicated partition) I delete the old files by hand.
A couple of my machines do support EFI. On those, I set INSTALL=no in
genkernel.conf. I then run a custom script afterwards which maintains
directories /boot/EFI/gentoo and /boot/EFI/gentoo-old. Each of these
contains a file kernel.efi and another file initramfs. This is FAT, so
no symlinks. The script deletes gentoo-old, copies gentoo to
gentoo-old, and finally puts the new files in gentoo. I have EFI boot
records pointing to both, using initrd=\gentoo\initramfs syntax.
