thank you Scot, Bryan, Preston and others that will respond, i asked because i am going through a new hardware cycle... my last hardware cycle was between the 1.2.13 and 2.0.X linux kernel stages believe it or not... and back then... well, i always hand rolled a kernel optimized to the bare bones servers i would take and hand build. i guess that i built some solid "forward looking" units as most did not need to be replaced for many years... typically 5 or more and many were simply just upgraded in processor or DRAM and possibly hard drive space etc. Bryan, i noticed and noted the SATA /dev/sda etc type device assignment issues. ummmmm will SATA always have SCSI type device assignment or has/will a new assignment be created? i imagine that it would go so an ATA type device assignment eventually wouldnt it? bottom line is, just about every type of hard drive storage interface driver (as well as any other relevant driver types) is/are included in the CentOS linux distribution? thanks - rh -- Robert Hanson Abba Communications http://www.abbacomm.net
