It appears that the Debian developers have finally gotten to the ends of their tethers trying to deal with the foibles of GLIBC and its maintainer. There’s a post on Aurélien Jarno’s blog saying:
I have just uploaded Embedded GLIBC (EGLIBC) into the archive (it is currently waiting in the NEW queue), which will soon replace the GNU C Library (GLIBC).
He gives a list of reasons for the change, all of which seem to make good sense. My concern (like many others) is that I worry about the impact if they are unable to keep compatibility with glibc based distros – though it’d be nice if they followed Debian’s lead on this (which they may do if this leads to a much easier working relationship with the maintainers – which doesn’t appear to be that hard to achieve!).
Update: If you’re curious to see what packages will be affected there is a list of the Debian packages built from the eglibc sources available.
