@MarkBeepBeep :-
It's all rather subjective.......and very much depends on how the OS is set-up to function. We don't update at all in 'Puppy' Linux; for one, Puppy doesn't have an 'update mechanism', per se, and for another, Puppy's philosophy takes the view that "if it ain't 'broke', why try to 'fix' it"?
Our approach is slightly different. A Puppy can be installed and be "up-and-running" in around 5 minutes.....and since Puppies, generally speaking, are much smaller than most other distros (due to consisting of highly-compressed files that are decompressed into a virtual file-system in RAM at boot), if the user feels the need for newer versions of stuff then it's simple to just install and boot a newer Puppy.
In 5 minutes or so you can be running a newer Puppy, with a newer kernel and newer dependencies. That's less time than it takes for most distros to perform the update process!
Many of our provided apps come in 'portable' format - browsers in particular - and since browsers always need to be as up-to-date as possible, these mostly all have updaters built-in. So; you can have an up-to-date, secure browsing experience without the need to have to update everything else....
It might sound an awkward way of doing things, and it probably won't suit many geeks, but.....it works for us.
