I don't think so, since I did:
for i in /usr/local/font-collection/......./* ; do ln -s $i . ; done
reboot
time ls -l >/dev/null
newly created entries shouldn't b fragmented, I guess.

I will investigate, but it is the first time I look into that so
if you have a link to quick howto, great, otherwise I read through

Best wishes
Norbert
