Re: [CentOS] selinux policy remnant according to /bin/ls on CentOS 6.0 box
Jon, Its worth noting in C6 that you really should avoid using RPM to add/remove stuff and stick with yum. Yum now supports rolling back and forward package changes, but this is broken if you do things with RPM.

Each inode in the file system still has a security attribute attached. You need to walk through the file system and remove them, one at a time: #!/bin/sh if [ "$1" = -v ]; then verbose=y shift else verbose=n fi for F in "$@";do if [ -n "$(getfattr --absolute-names -n security.selinux "$F" 2>/dev/null)" ]; then [ $verbose = y ] && echo "$F" setfattr -x security.selinux "$F" fi done -- Bob Nichols "NOSPAM" is really part of my email address.

It has been my experience that after after disabling SELinux, all that is then required is a reboot. Alternatively, running 'setenforce 0', will disable it immediately. >> the >> RPMs?

I went back and reread your original question, and I realized you had already answered that. Anyway, you are correct, less is more.

Wouldn't that be easier than removing all I did not do so explicitly. But it is set to disabled as described above. I assume the rpm -e did that. So, there must be some other step missing.

[CentOS] selinux policy remnant according to /bin/ls on CentOS 6.0 box
I installed CentOS 6.0 on 2 different x86_64 boxen. Both originally had selinux installed and enabled. I never touched selinux other than to remove as much of it as I could via rpm -e. As far as I can tell, here are the remaining packages that have something to do with it: # rpm -qa | grep -iE 'sel|pol' checkpolicy-2.0.22-1.el6.x86_64 libselinux-2.0.94-2.el6.x86_64 libsepol-2.0.41-3.el6.x86_64 polkit-0.96-2.el6_0.1.x86_64 # Both boxen have those packages. However: 1) box1 still has files in /selinux whereas box2's /selinux is empty; 2) ls -l on box1 shows a '.' at the end of file/directory, which means a SELinux security context applies, according to https://fedoraproject.org/wiki/Fedora_11_FAQ#Why_does_ls_show_a_dot_.28..29_or_a_plus_.28.2B.29_at_the_end_on_the_file_modes_for_some_files.3F Any idea why box1 still seems to have an selinux policy applied, and how to un-apply it?
