Hi, cowdancer: unexpected WIFEXITED status in waitpid /var/lib/dpkg/info/tzdata.postinst: line 29: /etc/timezone: Cannot allocate memory So, the real bug is in cowdancer detecting a weird environment. The quick workaround would be recreating cowdancer chroot. cowdancer returns 'ENOMEM' for system calls it has failed to handle (could be anything, but better than nothing; ENOMEM is chosen because it's something that's handled by applications most often. this is documented in cow-shell.1 manpage). I don't really have a clue on why this is happening, but the error message will come when 1. fork/exec of '/bin/cp' is successful 2. waitpid(pid, status) of that is successful. (cp should have finished...?) 3. but the WIFEXITED(status) isn't true. regards, junichi -- [EMAIL PROTECTED],netfort.gr.jp} Debian Project -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.
