Subject: Re: linux project dir with many (15k) files un-guard-able

I guess I should have been clearer; I don't need or want to watch any
of the 15k files that guard is thrashing.  I want to ignore them; I
want to eliminate the disk activity that is slowing down the system.

Moving the dir with the 15k files in it (without symlinking back)
accomplishes this, but I do need those files in place in the project
to do development work.  I just don't need (or want) guard to watch
(or even seek/stat) them for rspec testing.

I am not experiencing the resource allocation problem ("user limit on
the total  number of inotify watches was reached") that I encountered
prior to increasing max_user_watches.

I thought ignore_paths would do what I want, but it doesn't seem to
help.
