You mean glabel the file system but still leave it as a normal device name in fstab? Sure, no problem there. The file system can either be mounted using it's /dev/adXX (or /dev/daXX) device name, it's label, or even the ufsid (assuming it is a UFS filesystem, see the section below the glabel example) So basically you can reboot after creating the label without changing the fstab if you wish and change it later when you are certain that glabel worked as you expected. > I would think that that would be about the > same things ad doing it from a mounted system in SUM. > Then, the last question... where does tunefs really come in? .. I ask > As others have said (and as explained in Handbook section 19.6.1) tunefs can only create labels for UFS filesystems. Glabel on the other hand is not filesystem specific, you can label anything (for example, you have already labeled the swap space which clearly is not a file system). That makes glabel more suitable IMHO when the purpose is to completely replace the device names in fstab. So in short: - If you wish to create permanent labels for anything including swap space and 'alien' filesystems as well as UFS, use 'glabel label' - If you wish to create temporary labels for anything including swap space and 'alien' filesystems as well as UFS, use 'glabel create' (I doubt this is very useful, but it is an option) - If you wish to create permanent labels for UFS filesystems *only* you have the option of using tunefs. - If you do not wish to create labels yourself and you are only interested in mounting UFS filesystems without using the device names, you can use the ufsid labels that are created automatically when the filesystem is first created. >From all the solutions, the only one that covers both UFS and the swap space and is permanent is the 'glabel label' command (hence the example in the Handbook) I hope this clears it up :) _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
