Is it practical? I never use anaconda, but that means you need to install anaconda on device you use as cold storage which increases the complexity.
Started the thread with restoration in mind, not creation of cold storage. The anaconda installation seems to save hours of time figuring out python / pip errors, which you will get for sure on these older systems. Since you need all kinds of software, my 'method' which is far from a cypherpunk way, I'm sure, is to wipe a disk, clean (encrypted) OS install, get required software and then disconnect that disk forever, before restoring from seeds. You could then create a new wallet if you wanted to, since it's offline forever. If I'm missing an obvious pitfall here, please let me know.
@NotATether, thanks for the explanation, appreciate it.
