Applied, thanks.

I'm unconvinced (especially given we have to close #5735 first) that
this can land into 0.22.1, but I'd be glad to see this improved for
a future iteration. Filed #6575 as a subtask of #6508 (incremental
upgrades: complete phase four), targetted at Tails 0.23.
I've quickly had the code above save the reason why an incremental
upgrade is not possible. The checks that are done, and the
corresponding codenames for that reason, are (in chronological order):
1. non-writable-device
2. not-installed-with-tails-installer
3. no-incremental-upgrade-path
4. not-enough-free-space
5. not-enough-free-memory
If one check does not pass, the others are not performed; in practice,
there might be multiple reasons why an incremental upgrade is not
possible, but we're only saving one. I think this should be enough to
substantially improve UX, though.
So, when advising the user to do a manual (full) upgrade, we can now
insert a sentence that's specific to the primary reason why we cannot
do an incremental upgrade, e.g.:
1. "Tails was not started from a writable device."
2. "The device Tails is running from was not created using
Tails Installer."
3. "The Tails project does not provide an incremental upgrade to
this version." (e.g. will be the case for 1.1, most likely)
4. "There is not enough free space on the Tails system partition" (a
bit too technical, but how to express that without having tons of
people nagging user support because, oh well, they have space
left on their persistent volume?)
5. "Not enough memory is available on this system."
Improvements are welcome.
Cheers,
