For the ecryptfs FS:$ stat -f -c %l . 143 python -c "import os; print os.pathconf('.','PC_PATH_MAX')" 4096 For a standard ext4: $ stat -f -c %l . 255 $ python -c "import os; print os.pathconf('.','PC_PATH_MAX')" 4096 So ecrypts limits NAME_MAX. Indeed, running the perl snippet with $dir set to 142 works.
OK I'll take the simple approach and skip those tests in that case. Patch attached. thanks, Pádraig.
