Some map selectors (this case is olny considering macro selectors) may
|
|
|
304803 |
be given the comparison value left blank, possibly with the intent the
|
|
|
304803 |
selector will not match so a mount will not be attempted, such as when
|
|
|
304803 |
the delay option is also given.
|
|
|
304803 |
|
|
|
304803 |
autofs doesn't implement the delay option but it shouldn't fail to parse
|
|
|
304803 |
these locations so that a valid locations in the list can be tried.
