Good to know. Interesting! Noting that escaping the [ would work,
but not applicable in this case.

Would ${A%/*}/ work?

-                DIR="${DIR%$TGT}"
+                DIR="${DIR%/*}/"

It also has the advantage that it doesn't cause a fork (afaict,
the loop is being executed for every file in a rootfs directory
structure, that could cause a lot of forks).

(Disclaimer: I haven't tested this)
