This is just the minimal update: the gofmt-created updates have been reviewed and edited to preserve original semantic intent, but I didn't review all existing comments to benefit from the new syntax. Signed-off-by: Miloslav Trmač <mitr@redhat.com>

|
|
//
|
|
// If your application needs to access a containers/storage store in rootless
|
|
// mode, then the following additional steps have to be performed at start-up of
|
|
// your application:
|
|
//
|
|
// package main
|
|
//
|
|
// import (
|
|
// "github.com/containers/storage/pkg/reexec"
|
|
// "github.com/syndtr/gocapability/capability"
|
|
// "github.com/containers/storage/pkg/unshare"
|
|
// )

// var neededCapabilities = []capability.Cap{
|
|
// capability.CAP_CHOWN,
|
|
// capability.CAP_DAC_OVERRIDE,
|
|
// capability.CAP_FOWNER,
|
|
// capability.CAP_FSETID,
|
|
// capability.CAP_MKNOD,

// capability.CAP_SETFCAP,
