The new aggressive strip option was added in dracut 058, which tell
dracut to build the initramfs stripping more sections of the ELF
binaries (basically strip .symtab, .strtab).
These section are only useful for debugging runtime failures, but in
kdump kernel, neccessary tools for debug any runtime failure are
absent, there is no point keeping these sections.
Stripping these section can help save some memory with almost no side
effect. So let enable --aggressive-strip by default.
Comparison of unpacked initramfs before / after enabling aggressive strip:
du -hs image image.aggressive-strip
31M image
29M image.aggressive-strip
