Re: Target-specific configuration, specifically busybox

I checked that and IFUPDOWN is still selected in there.

I firmly believe in this being my own fault.

I tried to grep the unpacked busybox source-package for 'select IFUPDOWN', I
believe that would give me direct dependencies. But there are none.

I then did a make menuconfig in that source directory and removed the applets
interactively. Then did a diff between the resulting .config and the one
logged by the T2 build.

This gave me:

< CONFIG_IFUPDOWN=y
< CONFIG_IFUPDOWN_IFSTATE_PATH="/var/run/ifstate"
< CONFIG_FEATURE_IFUPDOWN_IP=y
< CONFIG_FEATURE_IFUPDOWN_IP_BUILTIN=y
---
 > # CONFIG_IFUPDOWN is not set
 > CONFIG_IFUPDOWN_IFSTATE_PATH=""
 > # CONFIG_FEATURE_IFUPDOWN_IP is not set
 > # CONFIG_FEATURE_IFUPDOWN_IP_BUILTIN is not set
636,638c636,638
< CONFIG_FEATURE_IFUPDOWN_IPV4=y
< CONFIG_FEATURE_IFUPDOWN_IPV6=y
< CONFIG_FEATURE_IFUPDOWN_MAPPING=y
---
 > # CONFIG_FEATURE_IFUPDOWN_IPV4 is not set
 > # CONFIG_FEATURE_IFUPDOWN_IPV6 is not set
 > # CONFIG_FEATURE_IFUPDOWN_MAPPING is not set

So I checked my $target/busybox.config again. I had

O CONFIG_IFUPDOWN

And now added

O CONFIG_IFUPDOWN_IFSTATE_PATH
O CONFIG_FEATURE_IFUPDOWN_IP
O CONFIG_FEATURE_IFUPDOWN_IP_BUILTIN
O CONFIG_FEATURE_IFUPDOWN_IPV4
O CONFIG_FEATURE_IFUPDOWN_IPV6
O CONFIG_FEATURE_IFUPDOWN_MAPPING

And rebuilt.

Bingo. It does not build ifup and ifdown into busybox.

Thank you very much! That takes me an important step further.

Ciao, MM
