Hi Stephen,
Alternatively can we set the filesystem type to start with? So that the initial label is not unlabeled_t. If so where can we do this?
Thanks, Anamitra

Hi Stephen,
In the dmesg output we see the following selinux messages.

I assume that dbcfs is the relevant filesystem? So you are using mountpoint labeling, i.e. passing context= to the mount command with a specific security context to use, and the policy doesn't know anything about this filesystem type. So its initial label is unlabeled_t, and by passing a context= option, you are triggering a relabelfrom check to see if the mount program is authorized to set the context. You can just allow it in your policy. Should have been present even in RHEL5, I think.
