Invisible files don't have file names, so they cannot be put in the tiny shell script: > + (format > + #f "env >~a || /usr/bin/env >~a || set >~a; \ > +echo GUIX-CHECK-DONE >>~a; exit\n" > + temporary-file temporary-file temporary-file temporary-file)) Also, I just noticed that this tiny shell script isn't quoting anything, so you'll get in trouble if $TMPDIR (or was it $TEMPDIR, whatever) contains " or ' or \ or whatever. So to avoid messy and fragile escaping, I'd recommend to work with file descriptors. Greetings, Maxime.
