Package: sbuild Version: 0.63.2-1 Severity: normal I'm using sbuild with foreign chroots via qemu-*-static as described in[0]. I've noticed that in my armel and armhf chroots amd64 is present as a foreign arch within the chroot.
This means that when sbuild does the apt update/upgrade dance it is downloading/uncompressing/processing a second set of architecture package lists using the emulated binaries. It would be better to avoid such unnecessary work in this case because of the emulation overheads. I've also got amd64 as a foreign arch in my i386 chroot but that is less of a worry. The foreign arch configuration doesn't appear to be added (i.e. it is already there) when I run "sbuild --arch=armel" and I've found that it is present in the source chroots too. I logged into the source chroot and "dpkg --remove-architecture amd64" and it is not added back by sbuild. I think that sbuild-createchroot must have added it. sbuild-createchroot uses Sbuild::AptResolver, I wonder if it could be that via an interaction with c89125965a15 "Sbuild::ResolverBase: Configure dpkg foreign-architecture"? sbuild-createchroot seems to set HOST_ARCH but not TARGET_ARCH and the distinction between the two is is used in that changeset. I'm running 0.63.2-1 but I can't see any change in the git tree which seems relevant. I've been round all my chroots and run dpkg --remove-architecture and AFAICT things seem OK (although I've only tried one or two builds). Ian.
