filename~ looks like an Emacs backup file, and I routinely delete them when I find some. I would suggest to use an extension that clearly indicates "Whodunit" - I use ".postinst-bak" (or ".preinst-bak" etc.). > I would also like to know if dpkg makes any backups > when installing packages, and if I can rely on them > being present when removing a package. It takes care that no files are lost in the unpacking phase - if unpacking fails for some reason, dpkg stops and you end up with only the old files installed. But after that, all memory of older versions are removed, except that files that were conffiles in the old version and are nonexistant in the new one are kept. The .dpkg-old and .dpkg-new files come from conffile handling, see 10.7 in the Policy. Regards, Frank -- Frank Küster Inst. f. Biochemie der Univ. Zürich Debian Developer
