Latest pijul and linux2x. Run ./unrec-dir.sh, two issues - it failed and returned zero error code. Please check everywhere you return non-zero on any errors, this is important for future runs over test suite, set -e already everywhere.

$ ./unrec-dir.sh 
+ source ./functions.sh
+ cd ..
+ rm -rf repo
+ pijul init repo
+ cd repo
+ mkdir -p 1/2/3/4
+ echo mikeiscool
