supervised services
*If I boot my SMESERVER with a USB hard drive attached, it recognizes the drive. However, after unplugging the drive, then replugging, it no longer exists. Any ideas why?

Reportedly, some external usb hd's must be completely powered up before connecting the usb cable.

AIT-2, DAT and LTO seem to work well with variable block size.

===Supervised Services===
*Many services on SME are supervised, to see which are type
ps ax |grep runsv
To control them read the sv manual
man sv
*it seems that "sv u http-e-smith" gives no errors, even if the
service fails to restart, so you need to use "sv s httpd-e-smith" to check if it fails
(example: due to a httpd.conf error)
This is just the way that runsv (part of the runit package) works. The "sv u http-e-smith"
only sends a message to runsv saying that we want the service to be up.
runsv then will keep trying to get the service running.
