I think this would be better sent to the nsa selinux list for better discussion. The problem with your parsing of the /proc/mounts is that it would not give you an accurate idea of what supports and what does not support SELinux labeling. Also this can change over time. If I mount an ext3 file system with a context mount, then it will no longer allow you to set the file context. I think the best idea is just attempt to assign the context and if it fails, ignore the error. I guess you can report it, if in verbose mode as a warning. Others may have different ideas. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Fedora - http://enigmail.mozdev.org iEYEARECAAYFAkkhg4EACgkQrlYvE4MpobMPMgCgm+G/Pyrll2CKHUynWftA7Shq phMAnAwTXQQ+mQH33EjP20o9iM7gaVvE =eDjj -----END PGP SIGNATURE----- -- This message was distributed to subscribers of the selinux mailing list.
