I used the buster installer about 1 year ago,with a fully encrypted disk, thus a /boot/efi partition, a /boot partition then an encrypted lvm. /boot is now not large enough to even have 2 kernels on it, initramfs-tools cannot create the images. I see this /dev/nvme0n1p2 237M 92M 133M 41% /boot /dev/nvme0n1p1 511M 5.3M 506M 2% /boot/efi Is it possible to reduce /boot/efi and have some more room for /boot, or should I reinstall the computer ?
Um, the kernel is only about 5M in size. With 133M free, there should be plenty of room for multiple kernels. The initrd image is usually under 40M, so there should be room for the entire boot image to be duplicated. Note the current use is only 41%. You shouldn't need more space, per se, except that normally the initrd is temporarily uncompressed while it is being created. I think you could get around this by employing chroot.
To answer your question, I am given to understand /boot/efi is a vfat file system, so it should be possible to shrink it, move the /boot partition, and then expand it.
