This also gives you the option to give more helpfull pasword hints like “we believe your housband might have the same password as you, just ask him”.

Another issue also is differentiating between hidden requirenments, undocumented features (positive), bugs (negative) and developer choice made during coding of the legacy software which does not affect the program positively or negatively.

A LLM (or alternatively a tem of developers) could do a reasonable well job of repuducing all these features and behaviors in a new program. But at that point you have effectively just cross-compiled your code (and maybe refactored it a bit).

The real issue is in identifying essential and wanted features from all the features, even if you could magically extract all of them. And in most cases that requires a deep understanding of the target audience/customer, which I would argue no person (including the customer), let alone a LLM, just has without years of requirenment refinement.

Just out of curiosit, what do you gain from unmounting the fs? Depending on your reasoning, it might he an option to use a zfs filesystem, set it up so automatic jobs rarely run and then set a somewhat agressive disk spin down policy. That way fs info would be handled by the arc, not the disks and they would only spin up when an actual file is accessed.

At least I assume it would work this way. Look-Ahead reads or your explorer generating previews, etc. might well make thta option fail.

I had an issue setting up immich for my parents, whre the fs would stall too long for it to successfully get files. Missing media was just getting displayed as a grey box with a “missing media” text on them.

At the station it became apparent that a few of the escalators were working again by now. However, some entrypoints remained closed off.

And a few months later:
