FreeBSD uses kernel mode modules; so it makes it faster, but it makes the kernel "look" bigger. And to stave off a flame session, these comments are very subjective and many will argue on both sides, but the proof is in the pudding as far as I'm concerned - I run both and my linux is CRAP by my reckoning. My drivers on the linux break constantly, and render the system useless without a reboot (and I'm NOT saying that it is anywhere near as bad as Windows: if I only had a choice of the two the linux would win for stability). My FreeBSD's have NEVER needed rebooting except for extraordinary circumstances, and the top stats don't lie either. > Is it difficult to update the patch? > > > On 04/22/10 23:54, Paul B Mahol wrote: > > On 4/22/10, xyz wrote: > > > >> Hi > >> Thank you for your answer > >> But "I can't believe" that lighten the kernel of useless drivers, saves > >> only few bytes, by removing whole useless modules (sound, ata/sata, agp...). > >> Furthermore, I think about free space that could be save too, in the > >> hard drive this time. > >> Why for the same configuration, linux kernel is lighter than the Freebsd > >> kernel?
