Next time we bump RAM requirements: notify user at runtime if RAM requirements are not met
Latest update: #5502#note-14
Users with less RAM than recommended get confused because they can't start all the software they would like concurrently.
Tails should therefore notify the user when booting it on a computer that does not meet the hardware recommendations. This notification would be printed somewhere on the tails-greeter (#5496) (boot menu (#5528)) screen.
A more dynamic approach (possibly for a later iteration) could be to use http://www.hadess.net/2019/08/low-memory-monitor-new-project.html or similar; it could not only automate the detection of "how much RAM is needed for basic Tails usage" (instead of having to keep this knowledge up-to-date ourselves: if
low-memory-monitor complains during our test suite, it could be a clear sign that we need to either optimize our stuff or bump the documented requirements); it could also warn the user whenever their usage of Tails requires an amount of RAM that exceeds their hardware's capacity, which can happen even for systems that meet the documented minimum memory requirements.

- design UI
- code (python/Gtk)
- fetch the source code of the greeter at http://git.tails.boum.org/greeter/
- add a .py file in the tailsgreeter package to check for hardware requirements (Python)
- edit glade/persistencewindow.glade with glade
- code GUI glue in persistencewindow.py (Python/Gtk)

We now recommend much more RAM: https://tails.boum.org/doc/about/requirements (2GB)
This ticket exists precisely because users miss that page and try to start Tails on systems we don't support. So the fact Tails now needs more RAM makes this ticket more important, not less :)
- Subject changed from Notify user if hardware requirements are not met to Notify user if RAM requirements are not met
- Target version set to Tails_4.0
I'm renaming to "RAM" because that's the only requirement that we can warn people about after they manage to start Tails.
From https://data.firefox.com/dashboard/hardware, as of January 2019, only 1.4% of Firefox users had 1 GB of RAM. So, given our current resources, I don't think we should spend time on this for that many users. 11% of Firefox users had 2 GB. So, let reconsider this the next time we really have to boost the RAM requirements.
Maybe in 4.0?
