- *"/overlay"* is correct for bash [[, and works during an install in ash, but during a boot script in ash results in attempted filename completion and gives an operand error
- "*/overlay/*" works in ash [[, but shouldn't, since it doesn't work in bash [[
- the inconsitent ash behavior in install vs. boot script is likely due to the operating directory of the script in each scenario
- KernelSU or APatch have completely hidden directories/files so would not get recreated
- for .apk files with a config.xml the config.xml would not get recreated due to the 0-size/hidden .apk
