  • Committer: Teddy Hogeborn
  • Date: 2008-09-05 07:11:24 UTC
  • Revision ID: teddy@fukt.bsnet.se-20080905071124-9dq11jq5rfd6zfxf
* Makefile: Changed to use symbolic instead of octal modes throughout.
  (KEYDIR): New variable for the key directory.
  (install-server): Bug fix: remove "--parents" from install args.
  (install-client): Bug fix: - '' -  Also create key directory.  Do
                    not chmod plugin dir.  Create custom plugin directory
                    if not the same as normal plugin directory.  Add
                    "--dir" option to "mandos-keygen".  Add note about
                    running "mandos-keygen --password".
  (uninstall-server): Do not depend on the installed server binary,
                      since this made it impossible to do a purge
                      after an uninstall.
  (purge-client): Shred seckey.txt.  Use $(KEYDIR).

* README: Improved wording.

* initramfs-tools-hook: Use a loop to find prefix.  Also find keydir.
                        Remove "${DESTDIR}" from "copy_exec".  Do not
                        try to copy literal "*" if no custom plugins
                        are found.  Copy key files from keydir, not
                        config dir.  Only repair mode on directories
                        that actually exist.  Do not run chmod if
                        nothing needs repairing.

* plugin-runner.conf: New file.
