I'm pretty sure grub uses that file. I've never tested the theory. Why such a small /boot? My OS is installed on a fairly small 160GB hard drive. I made /boot about 400MBs and later wished it was bigger. I later wanted to put a ISO image there for sysrescue. If I were to set up a new system now with that same size or larger drive, I'd likely make /boot 1GB and maybe even 2GBs in size. The amount of space is not that large compared to the size of the hard drive. If one is pressed to save space that bad on a system, maybe they need a larger drive?? You mentioned following a guide on that size. I have to ask, just how old was that guide? I looked at the Gentoo install guide, it suggests 128MBs for /boot, which I think is to small. Whatever guide you were using, it must be old and need some updating. I'm not sure I'd follow that one until it was. Dale :-) :-)
