Well, it is *one* of the forums. 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.
