Re: looking for a corporate debian edition, with support
You might try UserLinux also at:
"Canonical offers professional support for Ubuntu on both desktops and
servers. Contact email@example.com for more information."
-- from http://www.ubuntulinux.org/support/paidsupport
you'd have to ask them about availability and response time though.. :)
that page also lists several third-party firms offering support.
