I have a feeling that that will go on forever - there are always
broken packages, not to mention improvements, especially on kernel side.
There's no stopping point, and that's not bad.

It seems that good time will never come, since there are always
other things to be done.

Any interesting details here, please?

It is not possible for some devices, and too hard on others
(due to lack of device support, for example, and need to provide
powerful showcase).

And here you provide solution to build image, not solving
issues for user (he installs application and expects
for package manager to install his locales for him
automatically. So, a bit of patching of ipkg is needed.
Any cons?
