Yes, there is some improvement, but I still seek a *factor* of 3 to 4
overall before cpio+gzip. All the slow coding persists.
$ time /abs/path/to/dracut-013/dracut --local --force test2.img
### [fixed-width font, please] contrast to dracut-011
real 59s +3s
user 26s +6s
sys 29s -2s
26.0MB output image + 11.1MB
69.0MB unzipped + 28.0MB
1947 files listed by cpio +328 files
483 .ko kernel modules +116 modules
## Note the results have gotten larger (time, bytes, files, modules).
## The input (and configuration) has evolved, too.
