hey Sam,
I looked into ways to try to teach the chroot detection tools how to
detect a chroot in a new pid namespace (which is actually the problem,
not the mount namespace), but I didn't find a good solution there.
However, it occurs to me that you can simply override the answer:
ln -sf ../../bin/true ${SW_IMG}/usr/local/bin/ischroot
echo 'DPkg::Path "/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin";' >
/etc/apt/apt.conf.d/99-usr-local-dpkg-path
unshare -p -u -f --mount-proc="${SW_IMG}/proc" chroot "${SW_IMG}"
"${CHROOT_SCRIPT}"
EXIT_CODE=$?
rm ${SW_IMG}/etc/apt/apt.conf.d/99-usr-local-dpkg-path
rm ${SW_IMG}/usr/local/bin/ischroot
That would have the added benefit of solving the problem for
other/future packages as well.
If we were to update kdump-tools to detect a chroot as described in
comment #7 (test build in
https://launchpad.net/~dannf/+archive/ubuntu/lp2043059 ), could you
update your script to do the above?
