Proposed Changes
Improve error message when CLI wrapper Exec fails
Right now if the k3s CLI wrapper fails to exec the extracted binaries (most frequently because /var is mounted noxec), it just prints a fairly hard to diagnose
FATA [0000] permission denied
error.This wraps the exec error in some context showing what it was trying to exec, to assist with troubleshooting.
Perhaps we could also check to see if the filesystem is mounted noexec and return an even more meaningful error, but there doesn't seem to be a particularly graceful way to do that.
