DESCRIPTION

Sdloop allows a file to be used as a sd device. By specifying a number of sectors, the device may be be a different size than the file. To configure /tmp/data as sdl0: with a 1024–byte sector size
echo config switch on spec l type loop//tmp/data!1024 >/dev/sdctl
To turn this device off,
echo config switch off spec l >/dev/sdctl
The configuration variable loopdev may be specified in plan9.ini(8) to configure a loopback sd device at boot. For example
loopdev=l!/tmp/data!1024
