Also have a look at The FreeBSD Handbook 19.8.1: http://www.freebsd.org/doc/handbook/geom-glabel.html You will conclude that ufsids (file system IDs for UFS file systems) are comparable to the automatically generated GPTIDs (partition IDs for GPT-style partitions). User-defined labels come in the flavours of UFS labels (which are associated to file systems) and GPT labels (which are associated to partitions) - even though partitions usually carry file systems. :-) -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
