Well, exactly as you say... if you want it to be, it can be still pretty
simple :)

I don't know any software which could be simplier and still so reliable
for mission critical usage.

yum install heartbeat

Very robust, very reliable, easy to configure, easy to use :-) We use it
for almost every critical server for about 3 years without any problem.

Directory index is a feature of apache, which:
- if there is a file named in DirectoryIndex directive (usually
   index.html) in the requested directory, then show it (i think this is
made by mod_dir)
- if not, then create a list of files, if you have mod_autoindex loaded
   and Options +Indexes in directory configuration
(I recommend http://httpd.apache.org/docs/2.2/mod/mod_dir.html and
http://httpd.apache.org/docs/2.2/mod/mod_autoindex.html)

I believe, this comes because your /var/www/html contains no index
mentioned in DirectoryIndex rule. What is the content of /var/www/html?

Thanks for your reply and your time,
i've reported it to centos bug tracking system. I will try it also on
RHEL and if it occurs, i'll sent it also to the RH.

I think, that dereferrence should occure (at least for my coreutils
version); man chgrp:
--dereference
affect the referent of each symbolic link, rather than the symbolic
link itself (this is the default)

Well, that's another point, but that's not my job here :( I realized
this behavior on shared home directories server. These homes are
used by Win domain in classrooms, on terminal services, etc. It's not my
business to control, if some users (or local administrators) create symlink
to their home directory... But maybe i should write some little audit
scrip, which would search for these...

thanks,
Tomas

just to be accurate, this doesn't happen when using --no-dereference and it is not
changing permissions to root, but to user who is the owner of the link, so:

[[email protected: r...@machine] home]# ls -la user/.openoffice/user/work
lrwxrwxrwx 1 nobody root 13 Aug 28 14:35 user/.openoffice/user/work -> /home/user
[[email protected: r...@machine] home]# ls -ld /home/user
drwxr-xr-x  66 user staff 4096 /home/user
[[email protected: r...@machine] home]# chgrp -R staff user/
[[email protected: r...@machine] home]# ls -ld user/
drwxr-xr-x  66 nobody staff 4096 user/
