I have separate /boot, /home, /usr, /var, and /srv.
With one kernel only, my / uses 112 M and /boot is 20 M (with a .bak initrd.img for some reason). /lib/modules is 66 M. So figure that each kernel takes (66+20) 90 MB, plus the base /, if you want room for four kernels plus room to update one of them, you need: 112 + (5*70) = 462 for / , plus 5 x 20 = 100 MB for /boot, for a total combined of 562 MB. So, on an older computer where the kernels should be kept under 504 MB, you'll need to keep /boot separate. Doug. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
