"Red Carpet has a nice package abstraction layer that allows us to support RPMs and DEBs transparently"

In this quote, Nat Friedman is describing the software application tool called "Red Carpet". He explains it as having a "good plan abstraction layer", which implies that it has an easy to use interface that simplifies the procedure of managing software plans. This layer permits Red Carpet to support both RPMs (Red Hat Package Manager) and DEBs (Debian Package Manager) seamlessly. This is substantial since RPMs and DEBs are two different types of package managers utilized in various Linux distributions. By supporting both, Red Carpet becomes a flexible tool that can be utilized across various Linux systems. Overall, Friedman is highlighting the convenience and effectiveness of Red Carpet's plan abstraction layer in managing software packages.
