Package: schroot
Version: 1.6.10-6+b1
Severity: important
Dear Maintainer,
I'm using schroot for building packages with sbuild using qemu-arm-static
binfmt handler in chroot environment.
/etc/setup.d/15binfmt handler script incorrectly tries to perform bind mount
while schroot session is stopping. This leads to the mount error and terminates
schroot session end. So such sessions couldn't be ended. So, 15binfmt script
should take into account current $STAGE value to properly handle requested
operation. My modified script shows example of such handling process:
for emulator in $(update-binfmts --find "$shell"); do
dst="${CHROOT_PATH}$emulator"
if [ ! -e "$emulator" ]; then
info "Missing emulator: $emulator; not enabling binfmt support"
else
if [ "$STAGE" == "setup-start" ] || \
[ "$STAGE" == "setup-recover" ]; then
[ -e "$dst" ] || { mkdir -p "$(dirname "$dst")"; touch "$dst"; }
mount --bind "$emulator" "$dst"
mount -o remount,ro,bind "$dst"
elif [ "$STAGE" == "setup-stop" ]; then
umount "$dst"
fi
fi
done
It includes modifications, backported from schroot version 1.6.10-12, line:
...
[ -e "$dst" ] || { mkdir -p "$(dirname "$dst")"; touch "$dst"; }
