Create open_perms context manager for custom or multiple writes.
Create generate_config for a small removal of redundancy.
0640 root:adm the resulting files.
So that we consistently return the same value from lsb_release() across
all calls that use dry-run, the function now accepts a dry_run argument
(defaulting to False). This way, in dry-run mode, the caller does not
need to supply the path to a specific example file anymore.
lsb_release(dry_run=True) -> will load examples/lsb-release-focal
Having said that, the caller is still left with the possibility to
specify the example file by using the path argument:
lsb_release(path="example/lsb-release-impish")
The path and dry_run arguments are mutually exclusive: providing both
will result in a ValueError.

Fix warning:
subiquitycore/tests/test_view.py:24
subiquity/subiquitycore/tests/test_view.py:24:
PytestCollectionWarning: cannot collect test class 'TestStretchy'
because it has a __init__ constructor
As reported in https://bugs.launchpad.net/snapd/+bug/1946656,
not-quite idle connections between subiquity and snapd are piling up and
causing issues when trying to restart subiquity. I don't really
understand why, but using a fresh session for each API access makes the
problem go away.
* TimeZone: autoinstall and API
Add support for Get/Set timezone methods. Get means that we inquire
with GeoIP as to which timezone is suggested. Non-availability of
GeoIP, or a previous explicit Set, means that we return the system
timezone. Set of timezone by Post results in set of the live system
timzeone, and queuing a set of the target system by way of cloud-init.
* Add clarifying comment about _request.
Move mock_app to common location.
Move run_coro to subiquitycore so that subiquitycore doesn't have to
reference things in subiquity, even for test.
Move task tracking things from mirror to geoip.
Server app owns the geoip instance.
Create EventCallback as an alternative to MessageHub that should
hopefully express clearer intermodule dependencies.
* locale - let it check interactive-sections again
* Turn Serial into a whole new screen
When in serial, first offer the rich/basic choice (or SSH button),
and only show the current welcome screen if we choose rich mode.
Add a back button on Welcome if we are on serial.
LP: #1919251
This fixes a problem where you drop to a shell and refresh subiquity
from that shell -- the client tries to restart but it is running in the
background and so crashes trying to modify the terminal settings. So
this kills the subprocess before restarting. This required the extremely
angry PR I sent before: forcefully killing the subprocess also crashes
the client before restart in a similar way.
Here is something you can try with a live server installer today: drop
into a subshell and type "kill -9 $$". The installer will crash with an
'Input/output error' from tcsetattr.
What's going on is some deep unix arcana: when the subshell exits via
signal somehow the shell's process group is still in the foreground
(even though there are no processes in it?) and calling tcsetattr() from
a background process is not allowed. So the fix for this is reasonably
simple (or at least: short): call tcsetpgrp() to put our process group
back into the foreground. A background process doing this gets sent
SIGTTOU, but if we ignore that, all is well.
Frankly this is all very strange and I would like a lie down now.
