[Bug 802985] Re: [lucid] /var/lib/dpkg/tmp.ci/preinst: 399: arithmetic expression: expecting EOF: "3.0-0-generic"

[Enrique Hernández Bello]

I attach a patch for /usr/share/debootstrap/gutsy to support fake-uname
wrapper[1] for LD_PRELOAD and workaround this problem.

# HOWTO #

Compile fake-uname.so as shown here:
$ gcc -shared -fPIC uname.c -o /usr/local/lib/fake-uname.so -ldl

(-ldl parameter at last of command line is important)
(fake-uname.so at /usr/local/lib is also important according to following patch)

Patch /usr/share/debootstrap/gutsy:
$ sudo patch -p0 fake-uname_support.patch

Use debootstrap with UTS_RELEASE variable like:
$ UTS_RELEASE=2.6.32 debootstrap lucid target_dir/
