Well, so I read what you say, and that makes sense, except for one detail: /usr/share/icons (where the individual cursors would be kept) is wiped out every time I reinstall my system; thus also my wide selection of mouse cursors (130 of which I never use) ought to disappear, and I would have to start over and reinstall them.
Is there anything more than empty directories in your /usr/local/ tree?
All my software extensions go on a separate filesystem mounted to /usr/local/ for all Gnu/Linux installations except AntiX and MX. Those two conscript /usr/local/ for their own use. /usr/local/share/icons/ here has only 5 icons in it, all for gtk-built software such as SeaMonkey, Palemoon and Firefox. /usr/local/share/applications has my custom made menu entries, while /usr/local/fonts/ contains fonts, /usr/local/bin/ has custom scripts, and other directories in /usr/local/ contain various static-built apps extracted from .bz2 and .tar.gz files.
