RPM Extension
EOS has Extension feature but it is not only SWIX file but also accepts standard RPM file.
It is okay to make a RPM that specialized for Arista or EOS and just use as naked RPM Extension. And you can use some Fedora 9 standard RPMs as is, without any customization for Arista.
(There is no guarantee of 100% compatibility of all RPMs of standard Fedora 9)
In this document, we choose fping-2.4b2-8.fc9.i386.rpm which is the one of standard Fedora Core 9 based RPMs to show the RPM Extension management. To see native SWIX based Extension management, see
Extensions.
