(A removable disk full of music) Linux allows this, sort of. You can label disks with tune2fs, and mount can find disks based either the label or filesystem UUID. This lets you have an fstab that looks like LABEL=server1usr /usr ext2 defaults 1 1 devfs/GEOM could do something similar via a /dev/disk/label/ namespace. For people on SANs, a way to identify a device directly by serial number or WWN might be handy (maybe also enabling multipath access). -- Dan Nelson dnelson@allantgroup.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-arch" in the body of the message
