2020-06-04	Drop nvim(1) dependency in diff_kernel	Wynn Wolf Arbor	-1/+3
	Commit 1b8d91f ("Use configuration file under /boot instead of /proc/config.gz") enables us to drop neovim as a dependency, since we can now access all configuration data through actual files. Use git-diff(1) (which has automatic paging & colours) if available to show the changes between kernel configurations, else fall back to diff(1). Since the exit code of diff utilities is >0 if inputs are different, ignore the exit code of the diff utility in test_diff() to continue like normal.
2020-06-04	Use configuration file under /boot instead of /proc/config.gz	Wynn Wolf Arbor	-4/+3
	kern(1) has been using /proc/config.gz as the source of the currently running kernel's config since its initial commit. Whilst this location is convenient because of its static nature, it does need a specific kernel option, IKCONFIG_PROC, to be set. Furthermore, it introduces a dependency on gzip(1) to decompress the file on the fly. Consequently, we need to stream gzip's output to commands or save it in a temporary file to access it neatly. Since Gentoo's default install script for the kernel, installkernel(8), places each kernel's configuration file in /boot, we can use this location to retrieve the currently running kernel's configuration instead and work around all of the above limitations. Of course we need to make sure that /boot is mounted before we try accessing any configuration files on there. We use the already existing code from install_kernel() for that.
2020-05-16	Mention the base template in kern.1	Wynn Wolf Arbor	-2/+3
	Since fragment merging will fail if the base template does not exist, make sure to mention it in the manual.
