i don't know if i'm the only one experiencing this: i recently upgraded from fedora core 3 to fedora core 5 and since then i cant boot the OS. i keep getting a prompt saying something about selinux. i don't know how to disable selinux. the only thing that enables me to use my computer is a knoppix live-cd. as you can tell, this is driving me nuts since i lose all my saved documents when i shut down or reboot. (the size of my files is also limited to the size of my RAM) i really need some help here. thanks guys.
Here ya go SELinux allows certain levels of control over what parts of Linux can be accessed by whom. This is very useful for servers, or certain daemons or services which are directly connected to the web, example: webservers, databases, etc. SELinux configuration in FC5 is nice in some places and confusing in others. Please attempt to try to make SELinux work for you. There are some resources listed below. If you suspect SELinux problems try the following: * Check /var/log/messages or run 'dmesg' for information * Try temporarily disabling SELinux at the prompt and try whatever command you were trying before: 'setenforce 0' and enabling after: 'setenforce 1' * Try modifying your SELinux Policy for your specific application using the 'system-config-securitylevel' application. Most common issues can be resolved here. More information: SELinux in Fedora Core 5 SELinux commands http://fedora.redhat.com/docs/selinux-faq/ http://www.crypt.gen.nz/selinux/faq.html To Disable SELinux In my protected environment I do not use SELinux as I am the only user on my machine and I have no open connections to the web. Although leaving SELinux does make any machine more secure if properly setup. I am not recommending you disable SELinux, however it may be an easier solution for those who don't need it. Disable SELinux: EDIT '/etc/selinux/config' Change: SELINUX=enforcing to: SELINUX=disabled Disable SELinux from grub. Previous method is recommended. EDIT /boot/grub/grub.conf (as above): ADD 'selinux=0' on your kernel line in grub. Have a work through this and then report back. It's most probably a graphics config issue causing the non boot..but with the security throwing errors we can't get that far..

I tried editing the SELinux config file using a text editor (from Knoppix), from a Shell script (Konsole) and even from the GRUB boot prompt. The edited text wouldn't save (apparently i didn't have enough privileges), the file wouldn't even show up on Konsole and I didn't have permission to change it from the boot prompt. Is there any other way to go about this?
Lost me there.. To make changes you will need to remount the filesystem read-write. Not being an any-time user of fedora/redhat I'm unsure if it's the same... try remounting the drive/root filesystem rw using your live cd. http://www-uxsup.csx.cam.ac.uk/pub/doc/redhat/redhat8/rhl-sap-en-8.0/s1-storage-basics.html FC5 users help me out here.. I don't know anything about this SE package.
