 #!/bin/sh
 
-chown -R 1000:1000 $FILE
+UID=1000
+base_dir="/srv"

+chown $UID:$UID "$FILE"
+dir=$(dirname "$FILE")
+# Fix parent directory's ownership until we hit the base_dir or a directory that
+# Already belongs to the user
+while [ "$dir" != "$base_dir" ] && [ $(stat -c %u "$dir") != $UID ]; do
+    chown $UID:$UID "$dir"
