CheckCryptsetupVersion checks the version of cryptsetup and returns an error if the version is not compatible; nil otherwise

func CurrentUser 

func CurrentUser(t *testing.T) *user.User

CurrentUser returns the current user account information. Use of user.Current is not safe with e2e tests as the user information is cached after the first call, so it will always return the same user information which could be wrong if user.Current was first called in unprivileged context and called after in a privileged context as it will return information of unprivileged user.
