If n= ot=20 would it be possible to add one somehow? There is glabel, but I think having a UUID embedded in the FS would be very= =20 handy for automation andwould prevent accidents that glabel can cause. So, there could be a gfsid module that reads IDs from the FS (NTFS, ext2/3,= =20 UFS) and creates device nodes to allow access. Linux has something like this (or rather ext2/xfs do) and NTFS appears to h= ave=20 a unique ID (or at least Linux thinks so :) Thanks.
