What's needed is that the first sector understands LVM (or whatever the file system is if there's not LVM). So if we put the root onto a "conventional" file system, the first sector would be the boot code - no GRUB/LILO or anything else needed (IIRC). Of course, then no parameters passed, no selection of alternate boots, etc. Just like the old days! :-) Simplicity has its strengths and weaknesses. > -- Bill ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

You can enlarge or shrink it if you want, remove it from swap first, but many people just create another LV and add it to the mix. I think the biggest benefit to swap on LVM is when working with software RAID1 on the main disks, where you don't need to worry about creating a special MD just for swap, md0 for /boot, md1 for LVM. Not really a beef, in my books though it's added partitioning and potentially wasted space, but disks are big these days, so what. >> Swap performance should be equally good whether it be raw disk, raw >> partition, LVM logical volume or even a flat file on today's kernels, >> but maybe there is something I am unaware of. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

I don't use swap on VMs, for fairly obvious reasons. I guess I could use file-based swap, so it's easy to turn off and recover the space after the install finishes.

Depends on what you want to use it for. I have successfully run CentOS on PIIIs with as little as 256MB of memory, but with limited functionality enabled, usually as a firewall, SAMBA server and/or web server. In all cases I took care during installation to install as little software as possible, disable all unnecessary daemons and use only the command line.
