These warnings are logged to the console when launching a rescue disk image based on FC5test2: md: anaconda(pid 581) used deprecated START_ARRAY ioctl. This will not be supported beyond July 2006 [twice] SGI XFS Quota Management subsystem device-mapper: 4.4.0-ioctl (2005-01-12) initialised: dm-devel program anaconda is using a deprecated SCSI ioctl, please convert it to SG_IO program anaconda is using a deprecated SCSI ioctl, please convert it to SG_IO program anaconda is using a deprecated SCSI ioctl, please convert it to SG_IO [quite a few times] To see these I simply booted up the rescue image, and then ran dmesg -s100000 | less and scrolled back.
Yup, noticed this too and it really should be fixed...
