This is not sursprising - most of them are generated by one "mega-package" (or rather a script generating the packages from the TeXlive info) in one go, and this pre-generates also the ls-R db at

/usr/share/texlive/texmf-dist/ls-R

that texlive-base comes with and that lists everything from that distribution that you may potentially install or not. No need for those packages to mktexlsr. It has been done for them already.

You mentioned two packages touching ls-R. Which is the other one, and how does it do it?

In fact, R-core calls mktexlsr from scripts, e.g.

But that very directory is among the ones that you list above!

That indeed is a valid point. The spec uses %{texmflocal} already to get the destination directoty right, and it should touch the ls-R for that dir only.

Thanks for the explanation. I thought that this may be the case, but I was not sure (texlive.spec is very large, I hadn't found the code which generates ls-R).

Yes, R-core is the other package.

Sorry, that was a copy-paste mistake. tetex-elsevier files are currently stored in /usr/share/texlive/texmf-local, so this is the right file:

/usr/share/texlive/texmf-local/ls-R


Thanks for fixing the packages so quick!
