- Although we long ago replaced the getPartitions implementation, the
test is still there, and on a machine with no /dev/sda (e.g. because
root is on nvme) the echo-awk-shell-pipeline can give an empty string;
this is turned into a QStringList{""} which has one element, while
the new version has 0 elements.
- Special-case the test that empty strings should be empty lists, rather
than 1-element lists with an empty element.
- Just read /proc/partitions and process it; split into columns,
add relevant bits.
- This implementation supports devices named "name", which the other
didn't (but that would be really weird).
The tests now pass.
- This is a tiny bit of TDD to replace the existing implementation
(a shell pipeline) with processing inside Calamares.
- The test fails right now, since the implementations are not
the same.
