Re: SELinux blocks access to device files when booting 2.6.32.* kernels (fc12)

I did some more debugging: booted both kernels in single user mode,
then listed the security contexts in /dev:

kernel-2.6.31.12-174.2.22.fc12:
$ ls -Zd /dev
drwxr-xr-x. root root system_u:object_r:device_t:s0    /dev
files in /dev are labeled according to
/etc/selinux/targeted/contexts/files/file_contexts

kernel-2.6.32.12-115.fc12:
$ ls -Zd /dev
drwxr-xr-x. root root system_u:object_r:unlabeled_t:s0    /dev
all files /dev are unlabeled_t

But
$ fixfiles check /dev
prints nothing.
