The way I am testing it - I simply delete .git-submodule-status (I used to
change it but deleting works as well) and then I get:
./scripts/git-submodule.sh: 74: ./scripts/git-submodule.sh: cannot create
.git-submodule-status: Read-only file system
because "git submodule update" returns 0 (as everything is up to date) but
updating status fails. Which is fine, I would just like to get a better
message as even after few days of reading this script, I do not remember in
what order I should pass submodules to scripts/git-submodule.sh. Yeah, I
can find it in output but even the name of script to run does not stick to
my brain :(
Something like this:
- test $? -ne 0 && error "failed to save git submodule status"
+ test $? -ne 0 && error "\"$GIT submodule status $modules\" failed to
save git submodule status"
