This commit adds support for LUKS2 behind a new `partition.conf` key:
`luksGeneration`.
A bit of context, LUKS2 is the default encryption operating mode since
cryptsetup >= 2.1.0 (See [Arch
wiki](https://wiki.archlinux.org/title/dm-crypt/Device_encryption#Encryption_options_with_dm-crypt).
It is considered more secured and allows additional extensions. It also
comes with Argon2id as the default Password Based Key Derivation
Function (`--pbkdf` option). So it's important to provide this as an
option for Calamares in order to make Linux installs more secure, for
those who wish to encrypt their system.
This commit was tested on a custom Manjaro installer with:
- grub bootloader with the [argon patches](https://aur.archlinux.org/packages/grub-improved-luks2-git).
- [rEFInd](https://wiki.archlinux.org/title/REFInd) bootloader with
unencrypted `/boot` partition because rEFInd [doesn't support booting
from an encrypted volume](https://sourceforge.net/p/refind/discussion/general/thread/400418ac/)
**Important consideration for distribution maintainers**:
- You need to have compile flag `WITH_KPMCORE4API` on
- If you are shipping with grub by default please note that you need to
ship it with the Argon patches. Example on Arch Linux: [grub-improved-luks2-git](https://aur.archlinux.org/packages/grub-improved-luks2-git)
- If `luksGeneration` is not found in partition.conf, it will default to
luks1
- Please test this on your own distribution as this was only tested on
Manjaro installer (see above).
Existing code reinitialized the layout, losing whatever
layout was set in the config. Refactor so that you can
access the partition-layout API, and change the default
FS through that -- which is the point of the code block
here in `doAutopartition()`, to look up the currently-
selected default FS.
Inspired by Santosh's work in #1903, #1759.
- the length parameter to diskDescription() is worse than
useless, because it doesn't say anything about what will
be done if there's more than one disk.
will be used in summaryq, reading from widgets not an option
section probably better suited for Config.cpp/h, since quite a bit of duplicated code from
createSummaryWidget
Re-use the existing message about partition type and size,
since I don't want to introduce another message with all the
specifics; give a works-always message instead.
The check itself is also straightforward, avoiding all of the
nuances and technically-this-might-work cases: FAT32, 300MiB+.
FIXES#607
Modules nearly always have a Config and either a Job or ViewStep
as their "top level" components. Everything else is implementation-
detail. The *partition* module was unusual in that those two
"top level" components were tucked away in subdirectories.
Shuffle them to the top: this makes it more clear that these
two files are there to coordinate the module.
