[Solved]Right size for /boot

Which is, in your opinion, the right size for a /boot partition? Some guides suggest 50-100Mb, other 10Gb! hmm
Who's right?

Re: [Solved]Right size for /boot

I have 4 kernels in /boot totalling 42MB, so 50-100MB should be more than enough.

Re: [Solved]Right size for /boot

My boot is 200 M and contains 3 kernels + memtest + some splash images grub2 uses all of which take up only 18 M.  I would vote for 100 M as well.

Re: [Solved]Right size for /boot

Having /boot 10GB big would be just huge waste of space. I don't know what guide did you read, but the author was probably recommending placing /boot folder on the system partition, in this case 10 gigs may sound reasonable, but as others said before:  100 MB is enough.
