Created attachment 236097 [details] strace of nscd
Weird how it seems to be failing repeatedly to create a device node (with NULL pathname???) mknodat(7, NULL, 0) I did a quick nscd strace on my x86 system for comparison, and there was no creating of device nodes going on, successful or otherwise.
nscd is part of glibc; not for base-system should test glibc-2.11 as we're stabilizing that ... not going to be adding any fixes to glibc-2.10
works with glibc-2.11.1
