Yes. These are, as you mention, created by Anaconda's hacked init, out
of the full chart hardcoded in the devnodes[] array.

See devMakeInode in isys/devNodes.c. You'll see references to 's' 'd'
and 'h' 'd' and so forth. This is called from makeDevInode, in
isys/isys.c.
The code that you want is in iutil.py:

I hope this helps you understand the source code.
