/var/cache/fonts : Locally-generated fonts (optional)

The directory /var/cache/fonts should be used to store any dynamically-created fonts. In particular, all of the fonts which are automatically generated by mktexpk must be located in appropriately-named subdirectories of /var/cache/fonts.

Other dynamically created fonts may also be placed in this tree, under appropriately-named subdirectories of /var/cache/fonts.
