A 4M partition for /boot should be enough to hold enough kernels even for those who love experimenting with serveral versions... ...and if not, just give /boot 8M... > > But what if ... you want to resize the root? > > > Even when booting via initrd, you cannot resize the root while it is > > mounted. > > Actually, it IS possible to resize mounted ext2 filesystems with my > online resize tools (LVM is required, of course).

Ok - I knew that page but I donnow how stable this is, so I didn't include it in my argumentation. > Good luck on your project. I think this is a much better solution than > using initrd, since it is more like a normal system. It is tested for some weeks on two systems @myhome and Peter has two systems up this way since last weekend (Peter: correct me if I'm wrong with that date...). I think the idea has proven to be handable and reliable now I'd like to find an easy way to install such a system. And even if it is not needed today, somewhen LVM might be changed in a way that stopping it cleanly on shutdown will become a must. So I feel better having an init.d script starting and stopping LVM and I have no idea on doing this with an initrd based system... ...and if all else fails, I can access /boot and / with standard rescue disks... Bye for now! Ulf.
