FreeBSD 10.1 RC4
FreeBSD è un avanzato sistema operativo per moderne piattaforme server, desktop, ed embedded. Il codice di FreeBSD ha subito più di trent´anni di continui sviluppi, miglioramenti, e ottimizzazioni.

Note di rilascio

The fourth RC build of the 10.1-RELEASE release cycle is now available
on the FTP servers for the amd64, armv6, i386, ia64, powerpc, powerpc64
and sparc64 architectures.

This is anticipated to be the final RC build of the 10.1-RELEASE cycle.

The image checksums follow at the end of this email.

Installer images and memory stick images are available here:

If you notice problems you can report them through the Bugzilla PR
system or on the -stable mailing list.

If you would like to use SVN to do a source based update of an existing
system, use the "releng/10.1" branch.

A list of changes since 10.0-RELEASE are available here:

Important note to ZFS users on the i386 architecture: Using multi-disk
ZFS configurations on i386 (mirror, raidz-1, raidz-2, etc.) may cause
a kernel panic on boot.

Adding ´options KSTACK_PAGES=4´ to the kernel configuration is observed
to resolve the problem. Please *do* *not* upgrade your system with
freebsd-update(8) if using a multi-disk ZFS setup, since this will
override the kernel configuration with the GENERIC kernel.

This is also mentioned in the 10.1-RELEASE Errata Documentation:

Some of the changes between 10.1-RC3 and 10.1-RC4 include:

o Fix ATA CF ERASE breakage for certain CF cards.

o Fix a race in pmap_emulate_accessed_dirty() that could trigger
a EPT misconfiguration VM-exit.

Pre-installed virtual machine images for 10.1-RC4 are also available
for amd64 and i386 architectures.

The images are located here:

The disk images are available in QCOW2, VHD, VMDK, and raw disk image
formats. The image download size is approximately 135 MB, which
decompress to a 20GB sparse image.

The partition layout is:

. 512k - freebsd-boot GPT partition type (bootfs GPT label)
. 1GB - freebsd-swap GPT partition type (swapfs GPT label)
. ~17GB - freebsd-ufs GPT partition type (rootfs GPT label)

Note to consumers of the dvd1.iso image: The packages included on the
dvd will not be recognized by bsdconfig(8), and the cause is being
investigated. The packages, however, can be installed manually.

To install packages from the dvd1.iso installer, create and mount the
/dist directory:

# mkdir -p /dist
# mount -t cd9660 /dev/cd0 /dist

Next, install pkg(8) from the DVD:

# env REPOS_DIR=/dist/packages/repos
pkg bootstrap

At this point, pkg-install(8) can be used to install additional packages
from the DVD. Please note, the REPOS_DIR environment variable should be
used each time using the DVD as the package repository, otherwise
conflicts with packages from the upstream mirrors may occur when they
are fetched. For example, to install Gnome and Xorg, run:

# env REPOS_DIR=/dist/packages/repos
pkg install xorg-server xorg gnome2 [...]

The freebsd-update(8) utility supports binary upgrades of amd64 and i386
systems running earlier FreeBSD releases. Systems running earlier
FreeBSD releases can upgrade as follows:

# freebsd-update upgrade -r 10.1-RC4

During this process, freebsd-update(8) may ask the user to help by
merging some configuration files or by confirming that the automatically
performed merging was done correctly.

# freebsd-update install

The system must be rebooted with the newly installed kernel before

# shutdown -r now

After rebooting, freebsd-update needs to be run again to install the new
userland components:

# freebsd-update install

It is recommended to rebuild and install all applications if possible,
especially if upgrading from an earlier FreeBSD release, for example,
FreeBSD 9.x. Alternatively, the user can install misc/compat9x and
other compatibility libraries, afterwards the system must be rebooted
into the new userland:

# shutdown -r now

Finally, after rebooting, freebsd-update needs to be run again to remove
stale files:

# freebsd-update install
