Removing netbase from an image

Removing netbase from an image

[Jack Mitchell]

I am attempting to remove netbase from a custom image. I would like to 
replace it with connman. I have added connman through 
EXTRA_IMAGE_INSTALL, however netbase is brought in via 
packagegroup-core-boot.bb which funnily enough has some very important 
features and I would like to keep.

What would be the best way to make this replacement. Should I copy 
packagegroup-core-boot.bb and keep a local copy, while keeping it in 
sync manually? Alternatively, I notice quite a few packages in 
packagegroup-core-boot have a VIRTUAL-RUNTIME_* define. Would it be 
worth having a VIRTUAL-RUNTIME_network ?= "netbase" which could be 
overridden?

Thoughts?

You don't want to remove netbase, you just want to remove the
/etc/network/interfaces file.  The rest of netbase is very important
to have.

Dig on the list and you'll find patches to split that file out but
they didn't get into 1.3.  Unless you're working against master and
willing to help get those patches tested and merged, the easy solution
is to use a .bbappend and ship an empty interfaces file
(meta-guacamayo does this if you want prior art).

Well, FSVO "very important".  There's very little in there which is
actually indispensible; /etc/hosts is probably the only file that I'd
consider to be all that important, and arguably it's a libc bug that
this one is necessary.  I don't use netbase itself in any of my own
images.

Even though I agree with Ross that you most probably want to override
the interfaces file I think it is nice to be able to override it and
the VIRTUAL-RUNTIME_network-base would be a good addition for it.
