makedumpfile's purpose is to dump the memory of a crashed kernel (from a newly kexec'd "crash kernel"), ignoring user memory and pages of zeros. It's possible to do this after booting the crash kernel through a normal init process, but to avoid needing to pre-allocate a lot of memory for the crash kernel, it's better if makedumpfile can run in the initramfs. For that, we want a statically linked binary (or else we have to copy the libz, libelf, and libdw shared libraries also into the initramfs). It works just fine linked against libdw.a. -- John Wright <j...@debian.org> -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
