This is a follow-up question here
A suspect BUG. The parameter \alph doesn't work fine in my MAC OSX, when the counter is bigger than 6, in the section it is 2f, 2g, 2h, there will be something wrong. So I have to use \newcommand{\alphstring} and define \GlsAddXdyAlphabet{alph} from a to z manually same as greekstring and greek.
The mininal.tex:
I just copy the \sectionalph{Linux} of your solution code and then paste after it for some times.
\documentclass{book}
\renewcommand\thesection{\arabic{section}}
\usepackage[counter=section,xindy]{glossaries}
\newcounter{sectionalph}
\newcounter{sectiongreek}
\renewcommand{\thesectionalph}{\thesection\alph{sectionalph}}
\renewcommand{\thesectiongreek}{\thesection\greekstring{sectiongreek}}
\newcommand{\greekstring}[1]{%
