[clug] partitioning

[Kim Holburn]

I read an interesting book a while ago.  I forget it's name but it  
was something like "Optimising Linux servers" by someone from IBM.

They said that that start of the disk - cylinder 0 was around the  
outside of the disk and had the fastest access and so on until the  
centre of the disk which has the slowest access.  If you are  
partitioning a single disk then (as opposed to a raid) to make best  
use of that info you would partition like this so things that need  
that fast access get it, and things that virtually never change go  
near the end of the disk.

/dev/hda1		2Gig	swap	swap
/dev/hda2		16G	ext3	/var
/dev/hda4		>200G	ext3	/home

/dev/hda5		16G	ext3	/
/dev/hda6		64M	ext2	/boot
