It was pointed out to me by Gilles on

http://unix.stackexchange.com/ chat, that this syntax is probably not what
is required.

Currently the script has

  if [ -x /usr/bin/mktexlsr ] ; then
    /usr/bin/mktexlsr
    fi

which means, check the specific location /usr/bin/mktexlsr for an 
executable. If this exists, then execute.

However, if one allows for mktexlsr in non-standard locations, then one 
should rather have

  if which mktexlsr > /dev/null; then
    mktexlsr
    fi

which checks for any executable mktexlsr in $PATH, and if it exists, 
executes it.

As Gilles pointed out, this is the syntax used in 
/var/lib/dpkg/info/texlive-latex-recommended.postinst for example.

Comments?
