Ummm... a.) is this a bug?
b.) is it a known bug?
in my afs homedir:
e40-342f-2 70> cp /dev/null test
e40-342f-2 71> chmod 0 test
e40-342f-2 72> cat > test
abcdefg
e40-342f-2 73> ls -l test
---------- 1 cfields 8 Mar 22 13:38 test
e40-342f-2 74> cat test
test: Permission denied
e40-342f-2 75> cat >> test

e40-342f-2 76> ls -l test
---------- 1 cfields 11 Mar 22 13:38 test
e40-342f-2 77> cat test
test: Permission denied
whereas, in a local filsystem or with NFS:
e40-342f-2 81> cp /dev/null test
e40-342f-2 82> chmod 0 test
e40-342f-2 83> cat > test
test: Permission denied
I thought afs was supposed to honor the first three protection bits.
What's going on? It won't let me read, but will let me write, a file that
I own of protection zero.
Note also that the append attempt in AFS resulted not in an append,
but a rewrite. I expect that this is a bug in any case. (Append works
fine, though, if the protection is favorable.)
