On lwn.net, I noticed a potential problem in the mktexlsr script from
texlive : it uses predictable filenames and (arguably) will produce
mysterious errors if creating the temporary file fails.
This script is used to create the ls-R databases used by the
kpathsea library, and I think it gets run both during the initial
install, and if any TeX package is added or updated. I assume this
will be fixed upstream for the 2015 release which should happen soon,
so I'm not raising a ticket.
The source file is shipped in texk/kpathsea/ and installed to
bin/$TEXARCH/
The original diff for the binary version is:
--- texlive-bin.orig/texk/kpathsea/mktexlsr
+++ texlive-bin/texk/kpathsea/mktexlsr

The original reporte suggested that
treefile=`mktemp --tmpdir mktexlsrtrees.XXXXXXXXXX` || exit 1
would be better, but fedora have picked up the original, so I guess
that is already upstream. We prefer $( ... ) to ` ... ` so the
following will achieve the same thing:
sed -i 's/\(^treefile=\).*/\1$\(mktemp -q --tmpdir mktexlsrtrees.XXXXXXXXXX\)/'
\
/PATH/TO/mktexlsr
No doubt there are more concise ways of achieving this, and you need
to point to where the installed or source mktexlsr can be found.
