- Magisk Manager installs have busybox in the $PATH before extracting busybox from update-binary so an error from busybox ash (as sh) attempting to parse the x86 busybox like a shell script would be shown:
./bin/busybox: line 1: syntax error: unexpected "("
- this will only occur when ash tries to run a binary it can't handle, so basically only with x86 binary on an arm* device
