A quick research indicates that vfat volume labels have these restrictions:
- Maximum of 11 characters
- No * ? . , ; : / \ | + = < > [ ]
- No tabs

dosfslabel seems to comply to those restrictions. I couldn't find a
reference which says that labels may be 254 characters long.
Even when trying with mlabel, it shortens the string to 11 chars.
There were also some bug fixes in dosfstools [1] wrt dosfslabel and it
seems to work just fine here. It isn't a RH only hack either as it's
included in dosfstools upstream.

Looks to me, as if switching to dosfslabel should be safe, but I'd
appreciate if David and/or Martin could comment on this.
