Bug#399071: hostname can use uppercase letters.

[Masami Ichikawa <masami256@gmail.com>]

Package: netcfg
Version: 1.31
Severity: minor
Tags: d-i

Hello.

when I input invalid hostname netcfg said this message.
"A valid hostname may contain only the numbers 0-9, the lowercase letters a-z, and the minus sign.
It must be between 2 and 63 characters long, and may not begin or end with a minus sign."

so, from this message I thought that I can't use uppercase letters.
although, I can use uppercase letters.

I think the error message is not correct.

Cheers.
