	buildid.dir::

		Each executable and shared library in modern distributions comes with a

		content based identifier that, if available, will be inserted in a

		'perf.data' file header to, at analysis time find what is needed to do

		symbol resolution, code annotation, etc.



		The recording tools also stores a hard link or copy in a per-user

		directory, $HOME/.debug/, of binaries, shared libraries, /proc/kallsyms

		and /proc/kcore files to be used at analysis time.



		The buildid.dir variable can be used to either change this directory

		cache location, or to disable it altogether. If you want to disable it,

		set buildid.dir to /dev/null. The default is $HOME/.debug
