/usr/bin/test -r basically performs:
access(..., R_OK)
so the problem is definitely not in the libc, but rather in AFS _or_
in bash.
further search proves that I'm right: bash test builtin implements
access its own way (wtf?!) rather than using access. bash has to be
complied with -DAFS to use access(2), which it's obviously not under
debian:
$ cat a.sh
#! /bin/bash
test -r /etc/passwd
$ strace bash a.sh 2>&1 | grep passwd
stat("/etc/passwd", {st_mode=S_IFREG|0644, st_size=1710, ...}) = 0
reassigning.
