FreeBSD 10.1-RC4 Now Available

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 are included in the original announcement 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.

Changes between 10.1-RC3 and 10.1-RC4 include:

•  Fix ATA CF ERASE breakage for certain CF cards.
•  Fix a race in pmap_emulate_accessed_dirty() that could trigger a EPT misconfiguration VM-exit.

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.

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)

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-add(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 continuing.

# 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
