[cgl_discussion] RE: [cgl_specs] Use case - Live patching

[Howell, David P]

We're proposing a tool to address a common problem for telco 
applications. As this functionality is in use by many, it seems
to make sense that it be standardized for the needs of telcos 
and others who are concerned with high availability. There are
many tools provided by the distros that fall into this category.

Thanks,
Dave Howell

Then it should be stated very explicitely that this feature may only
be used for and by applications and that it is forbidden to patch
the underlying distro with it.

I am wondering why the distro then should even provide that
functionality?
Why doesn't the app provider take care of this himself then if it is
just
meant for his app?
