Thank you for adding the ctm bits in the page, I'm deeply intrigued by possibly solving this problem with bits *already* in base?!!

https://wiki.freebsd.org/action/diff/UsersFetchingSource?action=diff&rev1=6&rev2=7

However, even after reading the handbook page, I just don't quite understand how to use it on a modern system.  (The handbook page isn't too helpful, nor is the man page- perhaps I'm looking at it backwards)  Could you help clarify:

- does CTM go away with the CVS servers?
- do CTM-compatable patch/delta files exist on project repos?
- what is the cleanest path to using CTM? (e.g. is the patch you mention required)

Say I have a bare 9.1 install, no ports, haven't downloaded any base/src or ports yet.
How do I go about using ctm(1) to fetch REL or STABLE to /usr/src, command by command?

Best,
