Description Andrew Haley 2007-10-02 06:36:56 EDT
Description of problem:

If you install F8t2 in text mode, you get a file that is hard linked from two

[root@zorro ~]# ls -idl /etc/sysconfig/networking/profiles/default/resolv.conf
18759492 -rw-r--r-- 2 root root 70 2007-10-01 18:35 /etc/resolv.conf
18759492 -rw-r--r-- 2 root root 70 2007-10-01 18:35

This causes an SELinux failure at boot time:

Oct  1 17:14:01 zorro restorecond: Will not restore a file with more than one
hard link (/etc/resolv.conf) Invalid argument

The effect of this is that DHCP configuration of /etc/resolv.conf fails, and you
can't access any DNS servers.

How reproducible:

Every time

Steps to Reproduce:

Install f8t2 and choose the text mode installer, and select DHCP.
The easiest way to fix this would be to copy resolv.conf from 
/etc/sysconfig/networking/profiles/default/ rather than hard-linking it.
Comment 1 Daniel Walsh 2007-10-02 09:38:53 EDT
Or use symbolic links.  But this also looks like system-config-network/or
anaconda is not creating the file with the  right context?  

Could be related to Bugzilla #311481
Comment 2 Andrew Haley 2007-10-02 09:49:37 EDT
You're right, it isn't creating the file with the right context: I had to set
the type of /etc/resolv.conf to net_conf_t.
Comment 3 Chris Lumens 2007-10-02 16:50:45 EDT
I have verified that the latest build of anaconda sets the context on
/etc/resolv.conf correctly under text mode installations.
