Change references to the documentation sets that we still ship to reference the OpenAFS manuals instead of the IBM AFS manuals. Remove references to the IBM AFS/DFS Migration documentation, since that doesn't appear to be available anywhere any more, replacing them where relevant to more generic references to the DFS documentation. Add links to docs.openafs.org for mentions of the manuals in SEE ALSO, and standardize on one link format. Replace a few references to the IBM AFS Release Notes with the actual information in those notes, or drop the reference if it doesn't seem particularly useful.

=head1 DESCRIPTION
|
|
|
|
The fs copyacl command copies the access control list (ACL) from a source
|
|
directory to each specified destination directory. The source directory's
|
|
ACL is unchanged, and changes to the destination directory's ACL obey the
|
|
following rules:
|
|
|
|
=over 4
|
|
|
|
=item *
|
|
|
|
If an entry on the source ACL does not already exist on the destination
|
|
ACL, it is added.
|
|
|
|
=item *
|
|
|
|
If an entry exists on both the source and destination ACLs, the
|
|
permissions from the source ACL entry replace the current permissions on
|
|
the destination ACL entry.
|
|
|
|
=item *
|
|
|
|
If an entry on the destination ACL has no corresponding entry on the
|
|
source ACL, it is removed if the B<-clear> flag is included and is
|
|
unchanged otherwise. In other words, if the B<-clear> flag is provided,
|
|
the source ACL completely replaces the destination ACL.
|
|
|
|
=back
|
|
|
|
When using this command to copy ACLs between objects in DFS filespace
|
|
accessed via the AFS/DFS Migration Toolkit Protocol Translator, it is
|
|
possible to specify files, as well as directories, with the B<-fromdir>
|
|
and B<-todir> arguments.
|
|
|
|
=head1 CAUTIONS
|
|
|
|
Do not copy ACLs between AFS and DFS files or directories. The ACL formats
|
|
are incompatible.
|
|
|
|
=head1 OPTIONS
|
|
|
|
=over 4
|
|
|
|
=item B<-fromdir> <I<source directory>>
|
|
|
|
Specifies the source directory from which to copy the ACL. (Specifying an
|
|
AFS file copies its directory's ACL, but specifying a DFS file copies its
|
|
own ACL.) A partial pathname is interpreted relative to the current
|
|
working directory.
|
|
|
|
=item B<-todir> <I<destination directory>>
|
|
|
|
Specifies each directory for which to alter the ACL to match the source
|
|
ACL. (Specifying an AFS file halts the command with an error, but
|
|
specifying a DFS file alters the file's ACL). A partial pathname is
|
|
interpreted relative to the current working directory.
|
|
|
|
Specify the read/write path to each directory (or DFS file), to avoid the
|
|
failure that results from attempting to change a read-only volume. By
|
|
convention, the read/write path is indicated by placing a period before
|
|
the cell name at the pathname's second level (for example,
|
|
C</afs/.abc.com>). For further discussion of the concept of read/write and
|
|
read-only paths through the filespace, see the B<fs mkmount> reference
|
|
page.
|
|
|
|
=item B<-clear>
|
|
|
|
Replaces the ACL of each destination directory with the source ACL.
|
|
|
|
=item B<-id>
|
|
|
|
Modifies the Initial Container ACL of each DFS directory named by the
|
|
B<-todir> argument, rather than the regular Object ACL. This argument is
|
|
supported only when both the source and each destination directory reside
|
|
in DFS and are accessed via the AFS/DFS Migration Toolkit Protocol
|
|
Translator.
|
|
|
|
=item B<-if>
|
|
|
|
Modifies the Initial Object ACL of each DFS directory named by the
|
|
B<-todir> argument, rather than the regular Object ACL. This argument is
|
|
supported only when both the source and each destination directory reside
|
|
in DFS and are accessed via the AFS/DFS Migration Toolkit Protocol
|
|
Translator.
|
|
|
|
=item B<-help>
|
|
|
|
Prints the online help for this command. All other valid options are
|
|
ignored.

|
=head1 EXAMPLES
|
|
|
|
The following example command copies the current working directory's ACL
|
|
to its subdirectory called F<reports>. Note that the source directory's
|
|
ACL is unaffected. Entries on the F<reports> directory's that are not on
|
|
the source ACL of the current directory remain unaffected as well, because
|
|
the B<-clear> flag is not used.

=head1 PRIVILEGE REQUIRED
|
|
|
|
To copy an ACL between AFS objects, the issuer must have the C<l> (lookup)
|
|
permission on the source directory's ACL and the C<a> (administer)
|
|
permission on each destination directory's ACL. If the B<-fromdir>
|
|
argument names a file rather than a directory, the issuer must have both
|
|
the C<l> and C<r> (read) permissions on the ACL of the file's directory.
|
|
|
|
To copy an ACL between DFS objects, the issuer must have the r permission
|
|
on the source directory or file's ACL and the C<c> (control) permission on
|
|
each destination directory or file's ACL.
