For my diploma i'am implementing an ACL System on top of the 2.0.33 Kernel. It uses an modified Version of the ext2 (called ext2s for ext2-security) and supports POSIX ACLs. The System uses an ACL-CAche to speed up acl Operation. There is a Patch to the 2.0.33 kernel (ca. 600kb) with Acl-Tools such as mkfs and commandline acl modifikation... The only Backdraft is, that there are several extensions due to an enhanced security model called "hierachical Domain system" ;-) But These extensions are not so much. For use in an Produktion System they could be removed... The status of the code is alpha... regards Arne
