Why couldn't the kernel just to it automatically during the move? Well the kernel knows nothing about file paths. The real problem is the semantics of the mv command. The mv command maintains the file context of the source. So if you mv from user_home_t into httpd_sys_content_t it will stay user_home_t. cp on the other hand adopts the context of the destination by default. This mirrors the way DAC permissions work. The problem is people understand and have experienced DAC permissions. So when apache can't read a file you check the ownership and the permissions, but with MAC/SELinux you also need to check the file context. >> *_disable_trans was removed because it caused as many problems as it >> solved.

Good to hear it is being worked on. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.8 (GNU/Linux) Comment: Using GnuPG with Fedora - http://enigmail.mozdev.org iEYEARECAAYFAkfGQfUACgkQrlYvE4MpobO2qQCgn6N+PhvYhMmagyF7NV4t9w3+ 7L8AnRo8B0xpjAhzErxs/roaIlMezYrQ =WLDM -----END PGP SIGNATURE----- -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list
