12 Simplified modutils.
13
Denis Vlasenko0e2c93f2008-07-10 14:16:11 +000014 With this option modprobe does not require modules.dep file
15 and does not use /etc/modules.conf file.
Denis Vlasenko671691c2008-07-04 10:25:44 +000016 It scans module files in /lib/modules/`uname -r` and
17 determines dependencies and module alias names on the fly.
18 This may make module loading slower, most notably
19 when one needs to load module by alias (this requires
20 scanning through module _bodies_).
21
Denis Vlasenko0e2c93f2008-07-10 14:16:11 +000022 At the first attempt to load a module by alias modprobe
23 will try to generate modules.dep.bb file in order to speed up
24 future loads by alias. Failure to do so (read-only /lib/modules,
25 etc) is not reported, and future modprobes will be slow too.
26
27 NB: modules.dep.bb file format is not compatible
28 with modules.dep file as created/used by standard module tools.
29
Denis Vlasenko671691c2008-07-04 10:25:44 +000030 Additional module parameters can be stored in
31 /etc/modules/$module_name files.
32
33 Apart from modprobe, other utilities are also provided:
34 - insmod is an alias to modprobe
35 - rmmod is an alias to modprobe -r
Denis Vlasenko0e2c93f2008-07-10 14:16:11 +000036 - depmod generates modules.dep.bb

Denis Vlasenko3e8fd182008-07-10 23:42:36 +000038 As of 2008-07, this code is experimental. It is 14kb smaller
Denis Vlasenko671691c2008-07-04 10:25:44 +000039 than "non-small" modutils.
