* aerc: add space after definitions * aerc: only generate files, if options were set * aerc: improve file permission warning * aerc: remove redundant access to builtins * aerc: allow overwriting of derived values the order of merging the config subsets did not allow the user to specify outgoing, source and password command values, if they were previously derived from the SMTP, IMAP, Maildir etc config. The values from `account.<name>.extraAccounts` now have the highest precedence. Appropriate tests were added as well. * aerc: write primary account first

aerc: An email account was configured, but `extraConfig.general.unsafe-accounts-conf` is set to false or unset.
|
|
This will prevent aerc from starting, see `unsafe-accounts-conf` in the man page aerc-config(5), which states:
|
|
> By default, the file permissions of accounts.conf must be restrictive and only allow reading by the file owner (0600).
|
|
> Set this option to true to ignore this permission check. Use this with care as it may expose your credentials.
|
|
These file permissions are not possible with home-manger, since the generated file is stored in the nix-store with read-only access for all users (0444).
|
|
If `passwordCommand` is properly set, no credentials will be stored in the nix store.
|
|
Therefore, consider setting the option `extraConfig.general.unsafe-accounts-conf` to true.
