When there are multiple modules doing a thing and it really only
makes sense to have one of them in a given Calamares compilation,
the USE_<foo> variables allow you to select one, while ignoring
all the other implementations. If USE_<foo> is not set, all
implementations are included (as usual).
- The examples files are not harmless, so distro's should take a
explicit decision to install the config examples (instead of
putting files in /etc/calamares).
- Switch INSTALL_CONFIG to OFF by default **or**
- Make all the example configurations "harmless" or trigger
specific failure modes in the modules.
- Document that distro's should be creating their own set
of config and settings files and using those, rather than
relying on upstream example configs.
- Implement the required: module description field. This
would have prevented the plymouthcfg / grub failure fixed
in 3.2.1.
- Think about improving the available OPTIONs at a CMake level
to auto-fill SKIP_MODULES (e.g. it only makes sense to pick
**one** services module).
- Use YAML-CPP API for finding out if a node has a value at all.
- Asking for Type() of an undefined or NULL node throws an
exception, so the existing code didn't **actually** catch
cases where a required setting wasn't set at all.
- A valid line (as explained in the comments at the top of
the locale.gen file) is <locale> <encoding> (two fields),
so lines with more than two fields can't be valid locale-
listing lines. For them, pretend they name locale "",
which won't be matched.
- Improved debug-logging
- Fix the actual problem of listing locales more than once,
by listing them all, uniqified, at the end, with an explanitory
comment in the generated file.
- Be more accepting of what constitutes a locale-line; this allows
spaces before and after the `#` comment sign, but because we're
uniquifying, this doesn't cause duplicates.
- Because we write the enabled locales at the end, the full file
comment-header is retained un-mangled (instead of accidentally
enabling a locale mentioned as an example there).
Testing for existence of a file in the live system, and then
copying it in the target system, is not a recipe for success.
- Fix the restore-from-backup part.
- Document that your live and target system must both have
/etc/locale.gen if you want this to work at all.
just lines which might be comments, might be human-readable-text, or
might be example locales. Instead of modifying any comment-lines,
write enabled locales at the bottom of the file, while matching
very loosely with the comment lines from the file.
FIXES#940 (insofar as that is fixable)
Also make install for yum and dnf follow the documented syntax: options
(-y) before the command (install), even though yum and dnf also accept
the other order. This also makes it consistent with remove.
Untangle the shortcuts; Create and Cancel had an overlap.
Skip 'r' (Revert all changes) and 'e' (Edit) and settle on
'a' (which might also mean "Add").
FIXES#977
Introduce the notion of emergency modules and emergency jobs.
Initial use will probably center around the preservefiles module,
and possibly umount.
FIXES#928
- After a failure, skip non-emergency jobs.
- After running all emergency jobs, then emit failure message.
- In log, distinguish emergency and non-emergency jobs.
Any job can be an emergency job; emergency modules spawn
emergency jobs (but conversely, a non-emergency module
can spawn an emergency job explicitly).
A potentially emergency module is one that has EMERGENCY
(in CMake) or emergency: true (in module.desc) set.
Any such module must also set emergency: true in the
configuration of the module. This is to allow for
instances of a module that **don't** run as emergency
modules, alongside actual emergency ones.
Although the NO_INSTALL keyword could be specified for
Calamares plugins, it didn't actually do anything. Now
it does. A NO_INSTALL module does not install configs
or libraries.
