Missing cross dependency. Added to debian/xcontrol - I'll update the
patches this afternoon.

Need to work out how to remove this dependency still - it's 101kb of
waste. Once dpkg is able to filter on installation, it could be
rendered empty (it's only copyright/changelog/README stuff). The
gcc-4.x build is such a complex beast that it is hard to see why this
dependency is being added. I can probably stop any files being put into
the -base package but I'd prefer to drop the dependency entirely.

I'm looking to rebuild all the rootfs packages on buildd.emdebian.org
and update the versions in the repository over the next few days. The
new packages and the new support in emsandbox should ensure that the
resulting rootfs is installable as a starter.
Packages:
required="busybox dpkg libstdc++6 libgcc1 tzdata libc6
cdebconf libdebian-installer4 zlib1g gcc-4.2-base"
base="apt gpgv libreadline5 debian-archive-keyring
readline-common debianutils makedev base-passwd libselinux
libsepol1"
A smaller subset can be used if SecureApt is not to be supported:
required="busybox dpkg libstdc++6 libgcc1 tzdata libc6
cdebconf libdebian-installer4 gcc-4.2-base"
base="apt libselinux libsepol1"
Do we want SecureApt on the Emdebian target repository by default? IIRC
there is an option to apt to disable it. I can probably set that option
via emsandbox so that the same package could be used for both and then
we'd have two options : with SecureApt and without. Proceeding with
SecureApt on, for now at least.
A customised busybox can provide dpkg only if apt is also removed,
currently, due to a the limited option set supported by the busybox
dpkg. More testing on that would be appreciated once the packages have
been updated.
I'll work on the first package set - I know it's larger than originally
intended but that is principally due to libc6. I'm not sure how to
handle the glibc gconv files:
./usr/lib/gconv/ISO8859-7.so
./usr/lib/gconv/JOHAB.so
./usr/lib/gconv/MAC-IS.so
./usr/lib/gconv/IBM9030.so
etc.etc.
How should these be subdivided? How do we determine which gconv files
should go into which extra packages to reduce the total number
installed on any one device?
The rest of libc6 is big enough:
$ dpkg -c extra-deb/libc6_2.6.1-5em1_arm.deb | grep -v gconv | grep -v
" 0 " | cut -d' ' -f5- | sort -n
...

Any there that we don't actually need?
Most of those questions can wait until after CELF - my main objective
is getting the larger, SecureApt package set rebuilt and available in
the repository in time for CELF along with the final tweaks to
emsandbox so that the --second-stage support for debootstrap is usable.
The second stage works in manual mode with these packages, hopefully
there isn't much more than a few tweaks required.
I'm watching for dpkg 1.14.8, expecting a release this evening. I'll
probably release emdebian-tools 0.4.0 to Debian tonight (including
the latest changes to emsandbox) and then 0.4.1 to Emdebian with
whatever tweaks are needed for dpkg 1.14.8.

apt 0.7.6em1
base-passwd 3.5.11em1
busybox 1:1.1.3-5em1
cdebconf 0.115em1
