With commit 50e21c6 ("executor/linux: dump mount information when failed to open kcov file"), we got an unexpected result. /sys/kernel/ does not exist despite /sys/ exists. /proc/mounts cannot be opened despite /proc/ exists. If sysfs is not mounted on /sys/ and proc is not mounted on /proc/ , maybe other filesystems (e.g. devtmpfs, cgroup) are not mounted as well. Let's dump "/", "/proc/" and "/sys/", and then mount /proc/ and dump /proc/mounts .
