Hi there!

Small timeline update: I'm actually aiming at uploading the new glibc on
Friday, 3rd, so two days from now.

> Note that we are not impacted by the libcrypt removal as we
> haven't built libcrypt for glibc for a while. If some of your projects
> use a third-party malloc implementation, see at bottom to try a

> A number of potential issues have already been identified through a test
> rebuild done with a development snapshot of glibc. All glibc-related
> regressions have been identified and reported (thanks to Ravi Kant
> Sharma for his tremendous help on that front), and we're currently
> working our way through the list:
> https://bugs.launchpad.net/ubuntu/+bugs?field.tag=test-rebuild-glibc-noble
> There's a fresh snapshot package available in a PPA:
> https://launchpad.net/~ubuntu-toolchain-r/+archive/ubuntu/glibc
> (i386 build is currently broken, WIP)
> This upload usually has the immediate consequence of blowing up the
> autopkgtest huge queue, meaning any other package that uses this queue
> for its rdep tests will be directly impacted. In addition, the added
> load usually means there's a higher failure rate on tests (e.g. timeouts
> due to resource attrition). Furthermore, it is possible that a package
> built after the glibc upload would pick up a versioned dependency on the
> newer glibc due to changes in ABIs for existing functions. In that case,
> said package would need to wait until glibc has migrated, which can take
> a little while.
