Correct. I can reproduce it at will by upgrading/downgrading apt. I was of the impression that dpkg attempts to let packages work normally even during upgrades. That's why statoverride exists (to give new permissions to the file before the rename()), and why it renames files atomically, and why an upgrade is more elaborate than "tar old files" && "remove" && "unpack new files" || "unpack old files". Of course, the package may not work during the upgrade interval for some higher-level reasons (inconsistencies between files in the new/old versions or such). Why does apt's library include the libc6 version? I guess that ultimately causes the problem. I know that dpkg doesn't remove files in oldver but not in new-ver until the other files in new-ver have been unpacked; however, I don't know if dpkg attempts to unpack files only in new-ver before unpacking the files common to both. (That alone wouldn't fix the problem anyway, since the order of unpacking isn't guaranteed by a normal dependency). Am I wrong to think that library transitions (libfoo1 => libfoo2) and ABI changes (gcc-4.0) are supposed to be supported without things breaking during the upgrade interval?
