Hi group!
I've been managing a few production FreeBSD 6.2 servers for the last
year and I'm really impressed with the stability and performance. The
new year is coming, 6.3 is near out and I have a few questions about
upgrading to the next production release. I've thoroughtly read the
pertinent sections in the FreeBSD handbook and the last (excellent)
book of Michael Lucas (Absolute FreeBSD 2nd ed.) before asking these
questions.
1) Upgrading kernel and userland
Coming from a Debian background, I've updated kernel and userland
during the last months using "freebsd-update" for binary updates. I
understand that this is equivalent to tracking the source of the 6.2
errata (security) branch and rebuilding kernel and world.
However, I did not find any mention of a mechanism to upgrade from 6.2
to 6.3 release using "freebsd-update". Does this means that the only
procedure to upgrade between releases is to use "csup" to upgrade
sources (/usr/src) to the new release (6.3) branch and to rebuild
kernel/world? If this is true, does this way of upgrading prevent
future use of "freebsd-update" within the new release branch (6.3)?
2) Upgrading packages
I've installed my "external" applications using packages. I understand
that packages are ports that have been compiled for a specific
release. Thus, when ports are constantly upgraded (by security updates
or new versions), packages are not upgraded by their mainteners once
the release is out? Or maybe only security updates are added to the
packages included in a specific release?
Again, it is not clear for me how to upgrade from the old (packaged)
version of an application (which is tied to the 6.2 release) to the
new version of the application (which will be tied to the new 6.3
release). Do I simply need to desinstall (pkg_delete) the old version
and install the new version (pkg_add) after updating the $PACKAGESITE
to point to the package FTP directory for the new release?
Hope my question are clear! Many thanks for any hints and happy new
year!
Hans. |

Thanks for this link. I've read it carefully and i think it answers
the first question :
a) for 6.x releases, "freebsd-update" does not support upgrades
between releases. So, the only binary upgrade procedure seems to
involve "sysinstall" from a 6.3 release CD.
b) beginning with 7.0 release, a new option (-r) has been added to
"freebsd-update" and allows to upgrade between releases :
-r newrelease
Specify the new release to which freebsd-update should
upgrade (upgrade command only).
About binary upgrades of packages, i'm still puzzled..

An additional comment about my last post..
When you read the release notes from CURRENT (the link provided by
Torfinn) :
"Beginning with FreeBSD 6.2-RELEASE, binary upgrades between RELEASE
versions (and snapshots of the various security branches) are
supported using the freebsd-update(  utility. The binary upgrade
procedure will update unmodified userland utilities, as well as
unmodified GENERIC or SMP kernels distributed as a part of an official
FreeBSD release."
My understanding of this paragraph is that "freebsd-update" provides
updates within a release version (updates added in the errata branch)
BUT ALSO upgrades from an older release to a new one (e.g., 6.2 to
6.3).
However, when you read the online man pages for 6.2 or 6.3 releases,
the -r option for "freebsd-update" is not available. It only appears
in man pages for 7.0 release.
I don't have access to my servers now but i will check later if
"freebsd-update" from 6.2 release is indeed capable of upgrading
between releases.

That's my understanding as well. Although I'm still puzzled about the
proper way of updating a custom kernel during this process of errata
patching, before or after freebsd-update?

If I understand Lucas correctly then you do have the alternative to use
sysinstall which should be able to *upgrade* from one release or errata
level to another release (Lucas, page 380). But, as mentioned above, I'm
not an expert w.r.t. FBSD.

Here I'm lost and waiting for others ...

Michael

This page from the handbook suggests that freebsd-update should be able
to upgrade from one release to another:
http://www.freebsd.org/relnotes/CURRENT/relnotes/upgrade.html
Note: I have never used freebsd-update myself, so I don't know more
about it.

My understanding of the way that this works is like this: in preparation
of a new release the ports tree is "frozen" at a specific point in time,
and the package building process starts. After all packages are built
(and tested, fixed, rebuilt and so on), the ports tree is unfrozen again.
("Frozen" in this context just means that additions to the ports tree
are much more controlled; generally only security fixes and fixes for
other showstoppers go in in the "frozen" period.)
So in general; packages for a specific release (eg. 6.3-RELEASE)
contains whatever fixes (security and otherwise) present in the ports
tree at the time they were built. They are not (generally) rebuilt
after that before the next release cycle (if my understanding is correct).
Hope this helps some.

I can confirm that sysinstall does binary upgrades from one release to
the next. I have done this many times, and it works well (generally).

Same for me, never had a problem with binary upgrades.

This should be trivial if you use portupgrade with -PP option that
enforces binary only upgrade of all installed packages. So just
binary upgrade your system first, and then use portupgrade
(ports-mgmt/portupgrade).
It might be worth to you also to read this Dru's blog post:
http://blogs.ittoolbox.com/unix/bsd/archives/some-freebsd-pkg_add-magic-18897
I commented there on some strategies one may choose towards
installed package base.
