func FileExists ¶

func FileExists(path string) bool

func RemoveIfSymlink ¶ added in v1.2.0

func RemoveIfSymlink(path string) bool

RemoveIfSymlink removes path only when it is a symlink, and reports whether it did. A regular file, directory or socket at that path is left untouched.

This guards the shared paths kubesolo publishes itself into, such as the standard containerd socket: kubesolo installs a symlink there, whereas a container runtime managed by the host binds a real socket at the same path. os.Stat follows symlinks and so cannot tell the two apart; os.Lstat does not.
