Under 4.0-FreeBSD, Arla 0.22:
% cd /afs/andrew/usr4/rnw
% ls
# ... including a directory named 15740
% mkdir class
% cd class
% mv ../15740 . # 15740 is a directory
% ls 15740
ls: 15740: No such file or directory
% ls -l
ls: 15740: No such file or directory
total 8
drwxr-xr-x 3 34739 wheel 2048 Feb 24 20:09 ./
drwxr-xr-x 23 4294936499 wheel 6144 Feb 24 20:09 ../
% cd ..
% ls
# ... no 15740 here
% cd class
% ls
./ ../ 15740/
%
This can be repeated by moving other directories into . in the same style.
I'm guessing it's a cache coherrence thing--the directory really is moved
(and shows up that way on other machines), it just doesn't seem
immediately to be available for the stat performed by ls, perhaps cached
by the kernel?
Thanks,
