!!DESCRIPTION |

The __update__ daemon flushes the filesystem buffers at a |
|
|
21 |
regular interval. It has two modes of operation. By default |
|
|
22 |
it will wake up every 5 seconds and flush some dirty |
|
|
23 |
buffers. Newer kernels do not need a user space update |
|
|
24 |
daemon. This is automatically detected by __update__ |
|
|
25 |
which will simply exit. The traditional behavior of waking |
|
|
26 |
up every 30 seconds to call sync(2) can be forced |
|
|
27 |
with an option if it is deemed necessary. |
|
|

The following options are accepted by |
|
|
31 |
__update__: |
|
|
32 |
|
|
|
33 |
|
|
|
34 |
__-S, --use-sync__ |
|
|
35 |
|
|
|
36 |
|
|
|
37 |
Use the traditional behavior of calling |
|
|
38 |
sync(2). |
|
|
39 |
|
|
|
40 |
|
|
|
41 |
__-s, --sync-interval__ ''secs'' |
|
|
42 |
|
|
|
43 |
|
|
|
44 |
If using sync, wake up and call it every ''secs'' |
|
|
45 |
seconds. The default is every 30 seconds. |
|
|
46 |
|
|
|
47 |
|
|
|
48 |
__-f, --flush-interval__ ''secs'' |
|
|
49 |
|
|
|
50 |
|
|
|
51 |
Unless using sync, wake up and flush some buffers every |
|
|
52 |
''secs'' seconds. The default is every 5 |
|
|
53 |
seconds. |
|
|

__--help__ |
|

|
|
|

|
|
|

Print a usage message on standard output and exit |
|
|

successfully. |
|

|
|
|

__--version__ |
|
|
64 |
|
|
|
65 |
|
|
|
66 |
Print version information on standard output then exit |
|
|
67 |
successfully. |
|
|

|
|
|

|
|
|

__update__ should be started as early as possible during |
|
|
71 |
the boot process. If it is invoked by a non-privileged user, |
|
|
72 |
it calls sync and exits. |
