Hello, I'd like to set the io scheduler on some of the disks on our Dom0 (CentOS 5) to "deadline". The way I found to do this is with "echo deadline > /sys/block/sdb/queue/scheduler". What is the Right Way(TM) to set this automatically during boot? I sort of expected to use sysctl but it appears to only deal with pseudo-files under /proc/sys, not /sys. Also "sysctl -a" doesn't list such options. Searching the web also only comes up with the "echo" method mentioned everywhere. Is my only way to add some /etc/init.d script or /etc/rc.local line? Thanks, --Amos
