I could not successfully override locate-domination-stop-dir-regexp via .emacs because vc-find-root restores the default value.
STR:
override locate-dominating-stop-dir-regexp in .emacs with:
(setq locate-dominating-stop-dir-regexp "\\`\\(?:/uufs/chpc.utah.edu/common/home/[^\\/]+/\\|~/\\)\\'")
edebug-defun locate-dominating-file
stop at string-match, note value of locate-dominating-stop-dir-regexp
continue to next call to string-match (for a different dominating file)
re-check value of locate-dominating-stop-dir-regexp
You will find that for calls from vc-find-root the value of
locate-dominating-stop-dir-regexp will be the default (from files.el) as
opposed to the value in the .emacs setq
I maintain that locate-dominating-stop-dir-regexp might be better served
as an extensible list though others believe concatenating regexp after
regexp is the way to go.
An exchange on the google gnu.emacs.help forum can be found here: https://groups.google.com/forum/#!topic/gnu.emacs.help/wec_aPpUmqg <https://groups.google.com/forum/#!topic/gnu.emacs.help/wec_aPpUmqg>

I couldn't find the string "locate-dominating-stop-dir-regexp" anywhere
in the current Emacs sources, so I'm guessing this is no longer an issue
and is closing the bug report. Please reopen if this is a mistake.

`locate-dominating-stop-dir-regexp' is defined in files.el, so not so
hard to find.
Perhaps the reporter nees to sue `setq-default' rather than `setq'.

BTW, doesn't vc-find-root have the same purpose as vc-root-dir?
I don't understand the difference between them. Why the same
functionality under two different names? If they do similar
things, then we could expropriate vc-root-dir as a command
to visit the root dir in vc-dir mode.

Take a look at the usages.
vc-find-root is used in the implementations of vc-root-dir.

Ah, I see now, thanks. Then we could name a new command vc-dir-root
(that will use vc-root-dir to visit root dir in vc-dir-mode).
BTW, I tried `M-x vc-dir-search' (not bound to any key)
but it raises an error. Should I create a bug report?

OK, sure.

Or go ahead and fix it, I guess.
This patch seems to do the trick:

I think you're seeing the effect of this:
(defun vc-find-root (file witness)
"Find the root of a checked out project.
The function walks up the directory tree from FILE looking for WITNESS.
If WITNESS if not found, return nil, otherwise return the root."
(let ((locate-dominating-stop-dir-regexp
(or vc-ignore-dir-regexp locate-dominating-stop-dir-regexp)))
(locate-dominating-file file witness)))
vc-ignore-dir-regexp defaults to locate-dominating-stop-dir-regexp,
though, so could it be that you're setting
locate-dominating-stop-dir-regexp after you've loaded vc.el?
