Bug#563724: libc6 use syscall utimensat unimplemented by etch kernel

[Bill Allombert <ballombe@debian.org>]

Package: libc6
Version: 2.10.2-3

Hello Debian libc maintainers,

I run a sid chroot on top of etch, using the etch kernel linux 2.6.18-6-686,
and dpkg started to fail with
tar: ./preinst: Cannot utime: Bad file descriptor

touch also fails:

%mkdir /tmp/bar
%touch /tmp/bar
touch: setting times of `/tmp/bar': Bad file descriptor
strace report:
utimensat(AT_FDCWD, "/tmp/bar", NULL, 0) = -1 ENOSYS (Function not implemented)

It seems that the issue is that the etch kernel does not implement
utimensat. 

A similar report can be found at:
<http://lists.debian.org/debian-user/2010/01/msg00205.html>

Cheers,
Bill.
