Busybox configuration example?

Busybox configuration example?

[Gary Thomas]

I see mention of busybox configuration fragments in the mega
manual (section 5.9.7) but no explanation nor examples.

Can someone explain how I might control my busybox builds?
For example, I routinely add this to busybox*.bbappend:

   #
   # Force 'ifup' to wait longer for really slow links...
   #
   do_prepare_config_append () {
     sed -i 's/CONFIG_IFUPDOWN_UDHCPC_CMD_OPTIONS="-R -n"/CONFIG_IFUPDOWN_UDHCPC_CMD_OPTIONS="-R -n -T 1 -t 20"/' ${S}/.config
   }

which is just editing the confguration file to match my preferences.
Is there a way to do this using the "configuration fragments" mentioned
above?

Thanks

If I remember correctly there is one in meta-skeleton.

here is an example of busybox config fragment, that we use

https://git.linaro.org/gitweb?p=openembedded/meta-linaro.git;a=tree;f=meta-linaro/recipes-core/busybox;h=2c4a6b6b8b542b2eef04561d95a802d855ae7573;hb=master

i don't know if the config fragment would work for what you are
doing.. let us know ;-)

Thanks for the example.  I added this simple config fragment and it works fine.
   # Force 'ifup' to wait longer for really slow links...
   CONFIG_IFUPDOWN_UDHCPC_CMD_OPTIONS="-R -n -T 1 -t 20"
Of course, the comment is stripped in the final configuration file, but it
documents the purpose of the fragment.
