Hi, the backup files are there (see below). Perhaps, even though the
renaming and unlinking in strace look it is paired, somewhere between
the renames and unlinks xorriso is called by grub-mkrescue, and the unlinks
only takes place after the run; still, the files get deleted after
unsuccessful run of xorriso, hence they are not seen without your wrapper
script. There is restore_backup_atexit function in grub-install-common.c, which
calls "clean_grub_dir_real". The code is #ifdef HAVE_ATEXIT
Best regards,
Adam

So we have to watch the situation while grub-mkrescue is still running.
The following script will serve as xorriso in this run.
I put it into my "$HOME", but any otheri location should be ok.
It shall be used like this
grub-mkrescue -o output.iso --xorriso="$HOME"/xorriso_wrapper_ls_locale
Script text:
-----------------------------------------------------------------------
#!/bin/bash
# grub-mkrescue inquires features by running these arguments
if test "$*" = "-as mkisofs -help"
then
xorriso "$@"
exit $?
fi
# Look for the name of the /tmp directory with the GRUB2 files.
# It is the next argument after -r. But as default accept any /tmp/grub.*
next_is_dir=0
dir="."
for i in "$@"
do
if test x"$i" = x"-r"
then
next_is_dir=1
elif test $next_is_dir = 1
then
next_is_dir=0
if echo "$i" | grep '^/tmp/grub.' >/dev/null 2>&1
then
test -d "$i" && dir="$i"
fi
elif test "$dir" = "."
then
if echo "$i" | grep '^/tmp/grub.' >/dev/null 2>&1
then
test -d "$i" && dir="$i"
fi
fi
done
if test "$dir" = ""
then
echo "$0 : Cannot determine the path of the GRUB /tmp directory" >&2
else
echo "$0 : ls -l $dir/boot/grub/locale :" >&2
ls -l "$dir"/boot/grub/locale >&2
echo >&2
fi
# Finally do what grub-mkrescue expects
xorriso "$@"
-----------------------------------------------------------------------
I get as message output on stderr:

If this script does not show .mo~ files but the ISO does, then i am
out of ideas for now. (Crossing fingers ...)
Have a nice day :)
