Martin, I agree as of now it's better to refer mkfs.<FS> manpage and use it appropriately. I will write separate email to fsdevel mailing list.

For that you probably need to CC every filesystem development mailing list :) or as an alternative the common fsdevel mailing list. And yes, mkfs.reiserfs also takes -l. And the mkfs wrapper does *not* convert the option. So if you use mkfs -t reiserfs -L it doesn´t work. That is why I always use the mkfs.<FS> manpage and tool directly. I think all mkfs tools should do the blkid check and not overwrite an existing filesystem just so. -- Martin 'Helios' Steigerwald - http://www.Lichtvoll.de GPG: 03B0 0D6C 0040 0710 4AFA B82F 991B EAAC A599 84C7 L&T Technology Services Ltd www.LntTechservices.com<http://www.lnttechservices.com/> This Email may contain confidential or privileged information for the intended recipient (s).
