Hi everyone,

I have noticed something with emacs on GNU/Linux systems. When you edit something with Emacs, the SELinux context of the file doesn't stay preserved. This could be an issue when you edit configuration or policy files as root. A system setting file usually has a context like this,

system_u:object_r:usr_t:s0

but upon editing with Emacs it changes to

unconfined_u:object_r:usr_t:s0

I don't know how severe this is but maybe its worth looking at? Specially when this problem is absent for other editors. I tried this with nano, vim and mousepad. None of them had this issue. Can this be filed as a bug? Where would be the appropriate place to file this? The Emacs bugzilla or the bugzilla for my distribution?

Thanks for any suggestions.
