tlmgr check all...

[Karl Berry]

Hi Nelson,

          00_TIME.txt

TL does not distribute 00_TIME.txt. That's the mirmon test file.  So
evidently you're not running tlmgr check on a standard TL installation,
which is what it's intended for, and that probably explains the:
.. long list of 39759 files ...

	Warn: entry .:/usr/uumath/texlive/2019/texmf-local:/usr/uumath/texlive/2019/texmf-extra:/usr/uumath/texlive/2019/texmf-var//: in TEXMFDBS does not have leading !!
	Warn: entry .:/usr/uumath/texlive/2019/texmf-local:/usr/uumath/texlive/2019/texmf-extra:/usr/uumath/texlive/2019/texmf-var//: does not have an associated ls-R
	...
	Warn: tree !!/export/home/archive/share/lib/tex/texmf-local in TEXMF is not in TEXMFDBS but has !!

In a normal installation, for best reliability, every entry in TEXMFDBS
should have !!, and no entries not in TEXMFDBS should have it. (This is
the way the default texmf.cnf is set up.) Otherwise there is a risk that
a stale ls-R will be used. The comments in texmf.cnf explain more.

But again, since you're running on some kind of "supertree", this is
probably well known to you and not a problem. I certainly don't pretend
to understand the details your amazing setup at Utah :). --best, karl.
