Subject: Status of posix-ACL's

Hi,

i found at http://acl.bestbits.at the ACL-linux-project. Now i want to know,
if there is a plan to integrate posix-ACLs into the fs-part of the kernel,
e.g. into the VFS-Layer? Is there a general discussion about this anywhere?
What are the biggest problems? (i know that many userland-tools must be
changed for this).

Greetings

Jochen Dolze

I hope not. POSIX ACLs are crap. NFSv4 mostly follows NT.
Compatibility with NFSv4 and SMB (Samba's protocol) is important.

AFAIK there is no Support in User Land Programs required. You just have
additional tools for managing the ACLs . The main problem with ACLs are the
storage of the additional info in the file system. This is a hard job if you
want to have it for all/most file systems. Remy had a working Version for
ext2, but it never got very public.. dunno why.

NTs ACLs are somewhat messy cause they require too much scanning.
