I was wondering why they were using it. That explains it, thanks.

it could be opensuse also, that uses rpm too
iirc, opensuse is a german distro, or at least it's european, debian is american
It is german !
as i understand it, quite widely used by german companies
basically nobody else in the world uses it... it also has a slightly different tool called "zypper" iirc, that does something like apt for deb packages as zypper is for rpm, similarly there is dpkg and then there is rpm
i might be misremembering, i ran opensuse for a little while
