Package: fakechroot
Version: 2.15-1
Severity: normal
I've tried this with 2.15-1 backported to squeeze, and i've also tried
it with 2.9-1.1+squeeze1 on a squeeze system; i get the same failure
either way.
>From a squeeze system, I've done the initial part of a debootstrap
--variant=fakechroot as a non-privileged user to populate /tmp/root
with a sid install. The debootstrap fails after unpacking the initial
packages, at the start of running their postinst scripts.

when i used strace to figure out which libraries were being loaded, i
found that ld-linux from the non-multiarch host (squeeze) system looks
for the libraries in non-multiarch paths, can't find them in the
chroot, and so falls back to loading them from the parent filesystem:
...
open("/usr/lib/fakechroot/libacl.so.1", O_RDONLY) = -1 ENOENT (No such file or
directory)
open("/tmp/root/usr/lib/libacl.so.1", O_RDONLY) = -1 ENOENT (No such file or
directory)
open("/tmp/root/lib/libacl.so.1", O_RDONLY) = -1 ENOENT (No such file or
directory)
access("/etc/ld.so.nohwcap", F_OK) = -1 ENOENT (No such file or directory)
open("/lib/libacl.so.1", O_RDONLY) = 3
...
In particular, this is happening with ld-linux.so from 2.11 (squeeze)
when the targeted chroot is sid.
I believe this is another issue (like #650234) caused by the fact that
fakechroot can't override ld-linux.so.2. Since the host system's
ld-linux.so.2 in this case doesn't know how to search for multi-arch
library paths, it ends up failing to find the paths within the chroot.
In particular, it makes it so that "debootstrap --variant=fakechroot
sid" won't work on squeeze at all, even with a backported fakechroot
2.15.
