Dear Maintainer,

TeXLive include several "font-oriented" packages installing Truetype/Opentype
fonts, which may be useful to other applications. Some examples : Fira fonts,
New Computer Modern fonts (and then some), some language-specific fonts, can
be usefully used by LibreOffice.

Installing them for a user or systemwide is trivial : copy/symlink them to
~/.local.share/fonts (user), /usr/share/fonts (or /usr/local/share/fonts)
(systemwide). However, this trivial procedure may introduce further
non-obvious dependencies.

A better way might be to have these "font-oriented" packages to install these
fonts systemwide and to link them back to the TeX installation. However, this
might include in the user's use of fonts (a lot of) unwanted fonts cluttering
his|her everyday use.

An even better way should be to include (possibly in texlive-base) a small
utility proposing to the user (or the system manager) a list of all fonts
in the system and allowing him|her to mark them for TeX use, general use or
both, then updating (moving, fc-cache -r) as necessary.

There might be a lot of snags in this proposal, which is i fact a *policy*
 proposal, and it should be discussed seriously before implementation.

HTH,
