[CentOS] Very weird problem with handling symbolic links

Hi everyone,

I just discovered something very weird on a vanilla CentOS 7 installation. If I create a link to /tmp as a normal user, it looks like I can't remove this link anymore. Here's what this looks like:

$ mkdir test_link $ cd test_link/ $ ln -s /tmp/ link_to_tmp $ ls -l total 0 lrwxrwxrwx. 1 kikinovak kikinovak 5 Sep 17 10:56 link_to_tmp -> /tmp/ $ rm link_to_tmp/ rm: cannot remove ‘link_to_tmp/’: Is a directory $ rmdir link_to_tmp/ rmdir: failed to remove ‘link_to_tmp/’: Not a directory

I tried the same thing on a different box, running Slackware 14.2, and I can remove my symbolic link without any hassle.

I sense something is very wrong here. Any suggestions?

Niki
