[Buildroot] [PATCH] fs/ext2: add options for extra space and extra inodes

[Yann E. MORIN]

Jérôme, All,

On 2015-10-29 10:00 +0100, Jérôme Pouiller spake thusly:
> This patch has same purpose than 49964858f45d2243c513e6d362e992ad89ec7a45:
> 
>   On some machines, the network interface is slow to appear. For example,
>   on the Raspberry Pi, the network interface eth0 is an ethernet-over-USB,
>   and our standard boot process is too fast, so our network startup script
>   is called before the USB bus is compeltely enumerated, thus it can't
>   configure eth0.
> 
>   Closes #8116.

> interface is configured through DHCP at bootup. But, if user choose
> to write /etc/network/interface himself, he have to explicitly

I hope I'll have time to do a run test later tonight... However, I am
far from my RPis tonight (the whole week, in fact) but I'll try to sneak
downstairs to grab one... :-]

Regards,
Yann E. MORIN.
