Using the packages above and creating a local mini-repository I'm now
able to use debootstrap, along with some coaxing, to create a minimal
Debian filesystem based on my rebuilt packages. The first-stage
debootstrap (--foreign) is done under Debian armel and then with
chroot I then run the second-stage debootstrap.
Note that you don't actualy have to use --foreign in this case since
your host kernel can run the binaries for the target.
As the Raspberry Pi hardware is not shipping yet, I'm using QEMU
configured with an emulated ARMv6+VFP CPU and running standard Debian
armel to perform the installation of the packages.
Makes sense.
I'd say the next step would be to try and setup an autobuilding system
to build the rest of the packages. Now you have the root filesystem
built i'd suggest using a "build-up" approach (that is ONLY giving the
autobuilder access to the packages you have built). You may also want to
try and find a way to automate the check for armv7 code and run it
before introducing new packages into your archive.
You will also need to sort out a system to import new changes from
debian where you have not made source changes and notify you that
merging is required where you have made source changes (hopefully only a
handful of packages).
I'd suggest working with wheezy rather than sid since the churn rate
will be lower there and it's probablly what your users will want in the end.
However, as mentioned above, debootstrap needs some coaxing. During
the second-stage run of debootstrap, I'm getting dpkg errors that
abort the bootstrap process. I can re-run debootstrap again and it
will complete, but I would really like to understand why second-stage
debootstrap can't complete the first time and fix the issues. Also,
looking in the debootstrap.log file I see a number of dependency
warnings, but I'm not sure if these are just normal warnings which are
a side effect of how debootsrap calls dpkg to install packages on a
clean filesystem.
The specific error I'm running into is the following:
dpkg: regarding .../apt_0.8.15.10_armhf.deb containing apt,
pre-dependency problem:
apt pre-depends on libstdc++6 (>= 4.6)
libstdc++6 is unpacked, but has never been configured.
dpkg: error processing /var/cache/apt/archives/apt_0.8.15.10_armhf.deb
(--unpack):
pre-dependency problem - not installing apt
For some reason, debootstrap (or perhaps it is actually dpkg) can't
properly figure out that the libstdc++6 package must be configured
before it attempts to install apt. This is the only error of this
kind and I can't tell what might be different about how apt package
uses libstdc++ as a pre-depend. Other packages don't fail in this manner.
I've googled this error, but I haven't found specific information on
how to understand what's happening and fix the issue. I mostly find
bug reports that simply indicate the issue is not that uncommon.
Any insight someone could provide into debootstrap/dpkg pre-dependency
issues would be very helpful.
You are more likely to find someone who knows about debugging
debootstrap issues on debian-dpkg but I wouldn't worry too much about it
for now,
