A release candidate for XenCD v1.0 (1.0rc01) is now available:
http://files.wordzoo.com/xencd/xencd.iso.gz
http://software.wordzoo.com/xencd
svn://software.wordzoo.com/xencd/trunk
If no one flags any bugs with this release, it''ll be promoted to
v1.0final without changes.
There is a roadmap defined in the README, but the community hasn''t
weighed in much on the direction, so feedback is earnestly welcomed.
Changes in this version compared to 1.0pre02 include:
Major enhancements
- This is the first release candidate (1.0rc01). The package is no
longer considered experimental, as the package now has more
testing and reports of success.
- The default distribution includes a larger set of packages and is
now called "base" instead of "fat". The ISO is still
under 40 MB
and hosts with 368 MB RAM are still supported.
- The documentation has been significantly improved. Additional
introductory material appropriate to Xen newbies is included.
There is an explicit roadmap. The specific XenCD usage scenarios
targetted for support are listed. A list of common post-bootup
tasks is included. The supported boot options are documented.
Major bug fixes
- Memtest86 now works. It now uses a full 1.44 MB floppy image and
memdisk instead of only the binary.
- ttylinux instances now have xenU kernel modules available in their
rootfs.
- sysstat now starts collecting information upon boot, so iostat,
mpstat, and other statistics can been collected.
Additional enhancements
- Package changes:
- Replaced dhcp-client with udhcpc for compactness and simplicity.
- Added evms-cli for important command line administration of
volumes.
- Added htop to provide handy interactive process tree.
- Added time to base package set to support benchmarking better.
- Added x86info to base set for better error reporting.
- Added bing and iftop for network analysis.
- Added tree to help with browsing filesystems.
- Removed dhcp server as no default configuration would be
appropriate for the general population.
- Removed tethereal as it was too large.
- Removed scsitools as its functions were too low-level for common
usage.
- Booting:
- The exact variant and Xen tree used for a given build is
provided in the GRUB menu, the ISO filesystem, and dom0''s
/etc/issue.
- No EVMS volumes are mounted by default.
- metalog maintains fewer, but larger (500kb) files in /var/log by
default (daemon, mail. user, ppp, and crond directories
removed).
- Other:
- The ttylinux rootfs distributed by the Xen project has been
dropped from the XenCD distribution. It is no longer needed
since ttylinux rootfs''s are created on-the-fly during boot from
the original ttylinux distribution.
- More documentation updates: The ISO filesystem structure section
of the README was collapsed into the Implementation section.
There''s now a direct link to the Xen user documentation. The
TODO section was renamed ROADMAP. THe "early, buggy release"
caveat was removed. A list of known issues has been included in
the Caveats section.
- The ISO volume has been munged to use the full product tag but
shortened to fit into 32 characters.
- The package has been tested on a 440 BX/GX host (2x PIII).
- Wherever dd commands were used, the seek option is now used to
create sparse files.
- The build system now supports a lockfile to avoid concurrent
builds and can optionally cook just the standard release or all
releases at once. It also sets the path in order to work
properly from cron.
- A fourth virtual terminal was added to dom0.
Additional bug fixes
- The "pause for shell prompt" functionality turned on by the
"doshellpause" boot option now works. Instead of signal timeouts,
the timeout switch of bash''s read operator is used.
- The boot option for "ttylinux + xen0" has been removed as it never
seemed to function.
- The character used to switch to the Xen console has been changed
back to Control-A from the Control-X previously used.
- The /sys filesystem is included in dom0''s /etc/fstab by default.
- Link /etc/mtab to /proc/mounts so df reports accurate information.
- The build script no longer leaves metalog, chrony, and udev
running.
