At present, kernel documentation uses system serif font for body text.
Some people, however, objected to it and instead prefer that the
typography choice must be legible, consistent, and accessible (after
all, the audience ranges developers peeking into kernel internals to
ordinary users that skimmed through Documentation/admin-guide/).
To tackle the problem, follow Wikimedia's typography refresh [1].
For the font choices, instead of using web fonts as in previous
attempt [2], use:
* Linux Libertine, Georgia, Times for serif (used in h1 and h2
headings)
* system font for sans-serif and monospace
This allows for more readability and consistency without sacrificing
page load times and bandwidth, as the font choices is most likely
already available on many platforms.
