Ok, I have booted into rescue CD, and performed these steps:
1) (cd /usr-b; tar -cp --xattrs -f - .) | (cd /usr; tar -xp -xattrs -f -)
2) touch /.relabel
3) reboot
And I was able to get back into GDM and to log in as a normal
user using the login screen, however the boot processes did
report errors and the messages log as well:
1) restorecond: Will not restore a file with more than one hard link (/etc/resolv.conf)
2) SELINUX: avc denied {search } comm="ifconfig" name="lib" (7 times)
3) SELINUX: avc denied {read} comm="mount" name="locale-archive"
4) SELINUX: avc denied {read} comm="mount" name="locale-alias"
5) SELINUX: avc denied {search} comm="dmesg" name="lib" (7 times)
6) SELINUX: avc denied {search} comm="dmesg" name="share"
7) SELINUX: avc denied {search} comm="kudzu" name="lib" (7 times)
8) SELINUX: avc denied {search} comm="kudzu" name="share" (5 times)
9) SELINUX: avc denied {search} comm="arping" name="lib" (16 times)
10) SELINUX: avc denied {getattr} comm="arping" name="/usr/lib"
11) arping: libsysfs.so.1 and libsysfs.so.2
Note: most of these files have default_t assigned to these files... and
it says that for "arping", it needs to have netutils_t assigned.
It seems to me, that the only files I need to worry about are the above
libsysfs.so.1/2 needs to be relabeled and I am not sure what to do about
the /etc/resolv.conf file.
Can anyone advise what I can do at this point?
