Perhaps this is really a bug in test (i.e., bash), > but I don't see any good reason for ldd to be checking access in the > first place. /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. -- ·O· Pierre Habouzit ··O madcoder@debian.org OOO http://www.madism.org
