This is a mislabled file system. touch /.autorelabel; reboot Some how you got files without labels on to your system. Did you add a disk created on a non SELinux system.
Hi, I previously used opensuse (without selinux I think) and my /home directory is on a separate disk. I always move the original /home and create a /home symbolic link to this other disk.
Why not mount the drive on directly on your homedir, and then fix the labeling?
Hi Daniel, on the drive I have multiple directories, not only /home. For me, this way of using the disk is more flexible. What should be the way to add such a drive ? I think it's getting harder to set up a system for a novice user this way. As a novice user (well, concerning selinux at least) I don't know about selinux. Regards, Edwin
Edwin, I would argue that a novice user would never setup multiple home directories, most likely they do not even know what a home directory is. So you are clearly not a novice user. :^) What is your setup? Usually you can just label your random home directory as user_home_t and everything should work. # semanage fcontext -t user_home_t "/myhome/path(/.*)?" # restorecon -R -v /myhome
