@maintainer(s): after the bump, in case we need to stabilize the package, please let us know if it is ready for the stabilization or not.

There can be no bump.  sys-libs/uclibc is dead.  we should deprecate it in favor of uclibc-ng.

if its okay with security, we can convert this bug to a tree-cleaning bug for uclibc.

Sounds good, I created a PR to trigger CI for testing: https://github.com/gentoo/gentoo/pull/5004
Comment 4 Anthony Basile gentoo-dev 2018-10-14 12:20:35 UTC
sys-libs/uclibc has been removed from the tree,
