| 17 | With this option modprobe does not require modules.dep file
|
|---|
| 18 | and does not use /etc/modules.conf file.
|
|---|
| 19 | It scans module files in /lib/modules/`uname -r` and
|
|---|
| 20 | determines dependencies and module alias names on the fly.
|
|---|
| 21 | This may make module loading slower, most notably
|
|---|
| 22 | when one needs to load module by alias (this requires
|
|---|
| 23 | scanning through module _bodies_).
|
|---|
| 24 |
|
|---|
| 25 | At the first attempt to load a module by alias modprobe
|
|---|
| 26 | will try to generate modules.dep.bb file in order to speed up
|
|---|
| 27 | future loads by alias. Failure to do so (read-only /lib/modules,
|
|---|
| 28 | etc) is not reported, and future modprobes will be slow too.
|
|---|
| 29 |
|
|---|
| 30 | NB: modules.dep.bb file format is not compatible
|
|---|
| 31 | with modules.dep file as created/used by standard module tools.
|
|---|
| 32 |
|
|---|
| 33 | Additional module parameters can be stored in
|
|---|
| 34 | /etc/modules/$module_name files.
|
|---|
| 35 |
|
|---|
| 36 | Apart from modprobe, other utilities are also provided:
|
|---|
| 37 | - insmod is an alias to modprobe
|
|---|
| 38 | - rmmod is an alias to modprobe -r
|
|---|
| 39 | - depmod generates modules.dep.bb
