Re: [gentoo-hardened] SELinux updates

[Chris PeBenito]

Oops, the order matters on this.  You shouldn't reboot till the end:

1. merge new kernel sources (hardened-(dev-)sources users)
2. compile and install new kernel (hardened-(dev-)sources users)
3. merge selinux-base-policy-20040702 and etc-update
4. cd /etc/security/selinux/src/policy && make clean install
5. reboot
