Functions

func SetupTestCerts

func SetupTestCerts(dir string) error

SetupTestCerts populates the given test LXD directory with server certificates.

Since generating certificates is CPU intensive, they will be simply symlink'ed from the test/deps/ directory.

FIXME: this function is exported because some tests use it

directly. Eventually we should rework those tests to use NewTestOS
instead.

Types

type InotifyInfo

type InotifyInfo struct {
