Re: [PATCH] Remove unused snortupdateutility.js

["Peter Müller" <peter.mueller@ipfire.org>]

[-- Attachment #1: Type: text/plain, Size: 25242 bytes --]

Hello Leo,

indeed, this is orphaned. Thank you for catching it. :-)

We probably need to remove it during the upgrading procedure of the Core Update this patch will

Acked-by: Peter Müller <peter.mueller(a)ipfire.org>

Thanks, and best regards,
Peter Müller
