[linux-lvm] Characters allowed for vg name

[Gerrard Geldenhuis]

Thanks,
I did report it as a bug via Redhat support. I have ended up pasting the
mailinglist response in the support ticket after a week of no positive
response.

Would you aggree that a short note about allowable names should be added
to man lvm? If yes, then I don't mind creating a patch.

Regards
