For dynamic installation of extensible network operating system (ENOS) extensions, a network device downloads a full software image (SWI) having a signature and a directory containing software packages from an install source. During downloading, the network device modifies the full SWI on the fly, including reading and removing the software packages (SWIX files) from the directory, as each one is read, determining whether to keep it, for each “keep” SWIX file, extracting an ENOS extension and a corresponding signature, and storing them on a nonvolatile memory, resulting in a modified SWI with a signature but without the SWIX files. After download is complete, the signed ENOS extensions stored on the nonvolatile memory are verified to determine valid ENOS extensions for inclusion in an overlay filesystem which becomes a root filesystem for the network device. The signed modified SWI is also verified before booting the network device into the modified SWI.
