Add programs.borgmatic.backups.<name>.settings for native borgmatic
YAML and generate each backup file from it.
The location, storage, retention, and consistency options and the
section extraConfig options become deprecated aliases into settings.
Warnings name the affected backup. Legacy configurations without
overlapping keys produce the same YAML, and Home Manager symlink
exclusions still append to exclude_from.
Drop the assertions that rejected backups setting both or neither of
sourceDirectories and patterns, so native source patterns and
database-only backups work.
Consistency checks without a frequency were written as
`frequency: null`, which borgmatic rejects during configuration
validation. Omit null check fields so borgmatic applies its own
default.
This change converts redundant attribute assignments of the form `a =
a;` or `a = someSet.a;` into cleaner `inherit` statements. This reduces
verbosity and follows common Nix style for bringing attributes into
scope.
Statix Codes: W03 (manual_inherit), W04 (manual_inherit_from)
Also include statix and the rule in our configuration.
Instead of having to manually stub packages that should not be
downloaded we instead automatically stub all packages (except a small
list of whitelisted ones). Tests can re-introduce the real package by
using the `realPkgs` module argument.
This commit changes the config format of repositories to the
soon-be-expected `{ "path": "repository-path", }`. The Home Manager
configuration allows a simple string (which will get translated), the
new format by directly using the path attribute, and the one with the
optional label attribute. More information about the background can be
found here https://torsion.org/borgmatic/docs/reference/configuration/
The configuration file format of borgmatic has changed in version
1.8.0:
https://projects.torsion.org/borgmatic-collective/borgmatic/src/branch/main/NEWS
This commit makes Home Manager generate borgmatic's configuration file
using the new format.
Even though the NEWS file indicates that old configuration files are
compatible, this is not 100% the case: empty sections work fine in old
borgmatic but stop working in new ones. I've reported the bug upstream
by email as I couldn't create an account on the forge.
