Functions

func NewAttachPoint

func NewAttachPoint(prefix string, c Config) p9.Attacher

NewAttachPoint creates a new attacher that gives local file access to all files under 'prefix'.

Types

type Config

type Config struct {
	// ROMount is set to true if this is a readonly mount.
	ROMount bool

	// LazyOpenForWrite makes the underlying file to be opened in RDONLY
	// mode initially and be reopened in case write access is desired.
	// This is done to workaround the behavior in 'overlay2' that
	// copies the entire file up eagerly when it's opened in write mode
	// even if the file is never actually written to.
	LazyOpenForWrite bool
}

Config sets configuration options for each attach point.
