The FreeBSD linux compatibility environment currently uses RPMs from Fedora 10. Unfortunately Fedora 10 is end of life since a while. For one of the RPMs (the pango one) we where aware of a security vulnerability. As we do not know if it is feasible to update the linuxulator ports to something more recent, I decided to setup a VM with Fedora 10 and generate a new RPM for the linux-f10-pango port. Thanks to Luchesar V. ILIEV for explaining me how to do this.
Setup of the VM
I used VirtualBox 4.0.4 on a Solaris 10 x86 machine. I configured a fixed size disk of 16 GB and kept the default network setup (after installing the guest tools / kernel modules I switched to virtio, as I was not able to do anything useful besides a ping) and RAM size. The CD/DVD drive was configured to use the image of the full Fedora 10 DVD for i386 systems.
Setup of Fedora 10
Booting the VM from the DVD leads to the graphical Fedora 10 install software (after chosing to install a new system on the console). There I accepted all the defaults, except for the software to install. I deselected the Office and Productivity group and selected the Software Development group. When I was asked if I want to install some additional RPMs I had a look at the complete list and installed some I thought are necessary. I do not remember anymore which ones I chose, but everything which looks related to RPM building is a good candidate.
After a while the install will be finished and you can boot into the new system (eject the DVD from the drive before reboot). After reboot chose to install the Guest Additions in the menu of the VM. This should mount the ISO image in the VM. As root execute the file for Linux. This will build some kernel modules for better integration (e.g. seamless integration of the mouse between your desktop and the VM). At this point I rebooted and configured virtio as the NIC. I also had to configure the network settings by hand, as the GUI tool did not safe all the settings correctly.
Update and install of required RPMs
After the VM was up and the network configured, I updated the entire system (chose System Update in the menu). To update the pango port, I had to install the libthai-devel RPM. I had the RPM for it (and all the files I need to build a new pango RPM) already downloaded, so I did a “yum install /path/to/rpm”. At this point I was ready to create the RPM build environment.
The RPM build environment
As a normal user I executed the command rpmdev-setuptree which creates the directory rpmbuild and populates it with some directories. Now you just need to find a suitable .spec file and put it into rpmbuild/SPECS, put the sources (and maybe patches referenced in the .spec file) into rpmbuild/SOURCES, and you are ready to go (I patched pango.spec for a more recent pango version, basically just changing the version numbers). If you want to have a custom packager and vendor attribute in the RPM, you can add a line for each to ~/.rpmmacros, e.g. %packager yournamehere and %vendor whateverisappropriate. I used my @FreeBSD.org EMail address as the packager, and FreeBSD as the vendor.
Building a RPM
I used rpmbuild –ba –target i386-redhat-linux-gnu –clean rpmbuild/SPECS/pango.spec to build the new pango RPM. If everything is OK, the resulting RPMs (a source RPM, a devel RPM, a debuginfo RPM and the RPM for the binaries) are in rpmbuild/RPMS and rpmbuild/SRPMS. For a FreeBSD port we just need the source RPM (to comply to the (L)GPL) and the RPM for the binaries.
The i386-redhat-linux-gnu string which is used for the –target option of the rpmbuild command is what seems to be used to build the Fedora 10 RPMs. After building pango, the RPM has i686-pc-linux-gnu in some filenames instead (the default value for this setup). The binaries seem to be compiled for i386, so there should be no problem even for old systems.

In the last days I took (and even had) the time to install a VM with Fedora 10, updated all the packages after installation, and created a new linux–f10-pango port (v 1.28.3). I did this because the port has a security vulnerability according to our VuXML DB and there where more and more reports in the last months from users which had a problem with this.
During the update of the port I noticed that the port does not contain a FORBIDDEN entry, just portaudit complains about it because there is an entry in the VuXML. That is not nice. I was told that the ports slush will be lifted soon (I need to bump some PORTREVISIONs), this means that I can commit the update probably tomorrow, just in time when the new RPM should hit the FreeBSD distribution infrastructure (MASTER_SITE_LOCAL is updated once a day from a specific folder in our home directories).
Thanks to Luchesar V. ILIEV for the nice writeup of what to install in Fedora 10 to be able to build RPMs, and the description of how to build your own RPM.

It seems I have a bit of free time now to take care about some FreeBSD related things.
As part of this I already committed the UFS/FFS related FEATURE macros which where developed by kibab@ during the Google Summer of Code 2010. The network/ALTQ related FEATURE macros are in the hands of bz@, he already reviewed them and wants to commit them (with some changes) as part of his improvements of parts of the network related code.
The GEOM related FEATURE macros I just send some minutes ago to geom@ for review. All the rest went out to hackers@ for review. The rest in this case is related to AUDIT, CAM, IPC, KTR, MAC, NFS, NTP, PMC, SYSV and a few other things.
If everything is committed, it should look a bit like this if queried from userland (not all features are shown, those are just the ones which are enabled in the kernel in one of my machines):

After working a long time with Solaris (I started with 2.5.1 at about the time when Solaris 7 was released in 1998), my current boss decided that it is time that I do a certification for it (clients like it). Two exams later I have it now:
Since yesterday I am officially an Oracle Certified Professional, Oracle Solaris 10 System Administrator.
The exam questions where a bit strange. I asked myself if a real admin was proof reading them or not, but most probably someone without much knowledge about Solaris administration just took the study guides and tried to make some questions out of it.
Anyway, my boss should be happy now, and I have something to add to my CV.
