I have tried to refrain to respond fastly, trying to find what you are talking about.
But frankly I think it will not change much my answer.
I did found:
which seems related to what you said about vim segfaulting during build.
I don't care too much that vim does not build.
I care that the installation process fail on daily images (maybe for months) (in part because of vim).
current seems to be the last released version:
I don't expect current to be the latest released version.
Maybe the term I expect is:
stable: latest released version
testing: latest build version where "default" installation does not fail.
unstable: automatically build each day
I think what is called current would be what I would expect testing to be.
Could we modify the installation process to make vim not in the base packages until it build again?
So that the installation process would work for "testing".
I have seen somewhere vim is considered "optional" but that does not seems the case for the installer.
Frankly I feel like asking that we sweep the dirt under the rug... I guess it is ok if you say everyone you do so and why. ;-)
