dev-manual: Read-thru edits for "Selecting an Initialization Manager"
Mainly changed the way I referred to Systemd and SysVinit. I was rendering them in a courier font, which was not correct.

5386 You might find that there are groups of recipes or append files
5387 that you want to filter out of the build process.
5388 Usually, this is not necessary.
5389 However, on rare occasions where you might want to use a
5390 layer but exclude parts that are causing problems, such
5391 as introducing a different version of a recipe, you can
5392 use
5393 <ulink url='&YOCTO_DOCS_REF_URL;#var-BBMASK'><filename>BBMASK</filename></ulink>
5394 to exclude the recipe.

5398 It is possible to filter or mask out <filename>.bb</filename> and
5399 <filename>.bbappend</filename> files.
5400 You can do this by providing an expression with the
5401 <filename>BBMASK</filename> variable.
5402 Here is one example:
5403 <literallayout class='monospaced'>
5404 BBMASK = "/meta-mymachine/recipes-maybe/"
5405 </literallayout>
5406 Here, all <filename>.bb</filename> and
5407 <filename>.bbappend</filename> files in the directory that match
5408 the expression are ignored during the build process.

5411 <note>
5412 The value you provide is passed to Python's regular expression
5413 compiler.
5414 The expression is compared against the full paths to the files.
