Ofcourse, you are compleetly right. tftp booting is also an option, if one can prevent the localnetwork to be compromised. Anyway I would go for the CDROM for the ease of use, sinds its lots easier to replace a CDROM in case of an kernel upgrade. On the otherhand, a lot of BIOSes can prevent the bootsector to be upgraded. We all know if one does this, it will make the system stop, and therefore getting a DOS, if anyone tries to upgrade the kernel. Btw what kind of hacks do you guys apply to your kernel / distribution and what distribution do you use? I'm using the sources of redhat which I rebuild, but am thinking about using the sources supplied bij immunix, any comments on this? Especially the stackguard compiler thingies look very nice - but haven't used it for primal systems. Cheers, Renee. ------------------------------------ Renee A.
