You seem to anticipate cross-platform incompatibilities, but mind that using NFSv4+ACLs on Linux is a problem all by itself. Essentially all of Linux userland is ignorant about NFSv4 ACLs, so even with basic tasks one tends to risk subtle breakage. Note that it's a client-side issue that also affects the cited commercial servers. To illustrate the point, just try the following sequence of commands on an arbitrary v4 mount on a Linux client: % touch aclfile % chmod 644 aclfile % nfs4_setfacl -a A::otheruser@xxxxxxxxxxx:RW aclfile % nfs4_getfacl aclfile # file: aclfile A::OWNER@:rwatTcCy A::otheruser@xxxxxxxxxxx:rwatcy A::GROUP@:rtcy A::EVERYONE@:rtcy % cp -p aclfile aclfile-copy.v4 If the NFS server and its backing filesystem natively supports NFSv4 ACLs, `cp -p` will 'just' lose the ACLs that don't correspond to mapped mode bits. If they're mapped to Posix ACLs, it's even worse, and the cp command that was supposed to preserve permissions, has also just granted write access to the group: % nfs4_getfacl aclfile-copy.v4 # file: aclfile-copy.v4 A::OWNER@:rwatTcCy A::GROUP@:rwatcy A::EVERYONE@:rtcy Kind regards, Daniel -- Daniel Kobras Principal Architect Puzzle ITC Deutschland +49 7071 14316 0 www.puzzle-itc.de -- Puzzle ITC Deutschland GmbH Sitz der Gesellschaft: Jurastr. 27/1, 72072 Tübingen Eingetragen am Amtsgericht Stuttgart HRB 765802 Geschäftsführer: Lukas Kallies, Daniel Kobras, Mark Pröhl
