[yocto] [bitbake-devel] Yocto: Add custom user to custom group in bitbake recipe

[Parthiban Nallathambi]

Hi Maxim,

space.bb --> chromium recipe in 
https://github.com/OSSystems/meta-browser/tree/master/recipes-browser/chromium

app.bb --> http-server.bb attached

I have created a group "www" in http-server_0.10.0.bb and trying to add 
"chromium" user to this group in chromium-x11_%.bbappend.

But the useradd command is failed: group 'www' does not exit.
