ones automatically cleaned out. This means more space (a few KBytes) will
be used since in a given run, several of the programs are called more than
once. But it also means important debugging information should no longer
be lost by the file being overwritten. The length of time to keep the
files is controlled by --with-debug-days (default: 4). The old flag

of amdump runs in a dumpcycle. The default is one run every day.
A value of 0 (the default) means the same value as dumpcycle.
A value of -1 means guess the number of runs from the tapelist file,
which is the number of tape used in the last dumpcycle days / runtapes.
If you don't run amdump every days, you must set runspercycle
otherwise amanda will noy be able to balance the dump. You must
set runspercycle to -1 if you want the same behavior as previous
version of amanda.
* Space to be use as holding disk can now be "use all space except ??? Kb"
using a negative value for the 'use' parameter.

* amdump, amflush and amcheck will use the log files as locks, so as
to avoid running concurrently.
* driver now supports configurable level-0 dumps in degraded mode via
new amanda.conf keyword "reserve"; see docs/WHATS.NEW for details.
* Configure now looks for vxdump and vxrestore in /usr/lib/fs/vxfs for Solaris
systems and will use it vxdump/vxrestore automatically on vxfs filesystems.
* New `killpgrp' setuid-root program, that kills estimate dumps even
if they are setuid-root.
Changes in release 2.4.0p1
* Fixed kerberos encryption
* New --with-owner configure option, to specify owner of installed files
* amcheck now checks for the existence of gnutar-listdir and of a
compressor on the server (for indexes and server compression)
* Implemented dumptype option `strategy skip'
* Updated to libtool 1.2a
* Minor portability-related bugfixes.
Changes in release 2.4.0
* Several security-related fixes, see docs/SECURITY for details.
* New configuration file syntax: dumptypes can now be used as keywords.
* New text database format, to replace dbm/ndbm/gdbm/db databases with
a more portable and user-friendly format.
* Index files are now sent through a separate TCP connection, as they
are generated, instead of being stored in /tmp. This breaks Amanda
protocol backward compatibility.
* Estimates are now performed concurrently, if maxdumps>1.
