So, this ’assert-no-store-file-names’ check in Makefile.am greps for

    -E "$(storedir)/[a-z0-9]{32}-" $(distdir) ;

which is really meant for source code; to catch the use of hardcoded
store file names.  Unfortunately, however ...

a commented store file name was added inside a code snippet.  Changing
this comment to something like

    // /gnu/store/...-tcc-boot0-0.9.26-6.c004e9a/lib/libc.a: error: 
'sigprocmask' defined twice

would pass the check, but this triggers a rebuld world.  So I am
proposing the attached patch that breaks the comment to pass the check,
and using unquoted string-append to  avoid a world rebuild.

Greetings,
Janneke

Subject: [PATCH] gnu: commencement: bash-mesboot0: Break store file-name in
 comment.

This fixes running ‘make release’.

* gnu/packages/commencement.scm (bash-mesboot0)[arguments]: Break store file
name in commend and add unquoted string-append to silence store file name
check.  The store file name check is meant for code, this file name was
unfortunately used is a comment.
