Nothing at the moment. In setting up this "play system" (personal server
for mail, web, and multimedia) I suddenly find myself reading man pages
and tutorials for a lot more subsystems than my brain apparently has the
capacity to handle at one time.

Ive mixed up what requires which more than once in the last few days.

Now, that being said, it will be a lot easier for *ME* if I always know
exactly where the SATA drives are located in the plain-old /dev tree and
if I can call them /dev/sdw or /dev/sdz rather than
/dev/disk/by-id/ata-WDC_WD2500YS-01S-WD-WCANY1955037

I added this to my local.rules and udevtest says it works great for the
first drive I already have installed:

KERNEL="sd*[!0-9]", IMPORT="/sbin/scsi_id -g -x $tempnode"
KERNEL="sd*[!0-9]",
ENV{ID_SERIAL}="SATA_WDC_WD2500YS-01_WD-WCANY1955037", NAME="sdw"

As I add the other 3 drives I just need to add lines to identify their
serial numbers and set them at sdx, sdy, and sdz.

Thanks,

Gerald
