I've been reading the official Debian install document, and I can't find an answer when it comes to partitioning how big the /boot should actually be. While there are recommendations for /var, /tmp, /root and /home
Hi Jen,
Not sure if this is the correct list to ask that question.
But anyway, you need space for at least three sets of unpacked kernel images
including generated initrd. For current x86 kernels, one set is roughly 75 MB.
So 250 MB should be safe for /boot size. But you need to ensure only 2 latest
kernels left, for instance, by executing 'sudo apt autoremove --purge' after
installing the latest kernel and reboot. That way, you will have needed space for
next kernel installation if needed.
