The latest glibc update breaks most sid installs on (typically leased) openvz platforms because it requires a newer kernel version that most openvz vendors advertize.
Most openvz run on kernels based on 2.6.32, often with significant updates. These platforms are an important segment, given how affordable they are. And Debian "stable" is often too archaic for many needs which fit nicely on a small inexpensive server. There should be a way to continue to use sid on these platforms. Adding a hold on libc6 only causes other problems, since so much now depends on 2.21 and apt will drop them if libc6 is held on 2.19. Is there another option to avoid the breakage? -JimC -- James Cloos <cl...@jhcloos.com> OpenPGP: 0x997A9F17ED7DAEA6
