func (*Chroot) RunCallback

func (c *Chroot) RunCallback(callback func() error) (err error)

RunCallback runs the given callback in a chroot environment

func (*Chroot) SetExtraMounts

func (c *Chroot) SetExtraMounts(extraMounts map[string]string)

Sets additional bind mounts for the chroot environment. They are represented in a map where the key is the path outside the chroot and the value is the path inside the chroot.
