Why the initramfs image created by dracut includes a small number of files in Red Hat Enterprise Linux 7
Issue
- The initramfs image file created by dracut is a cpio archive. Normally, it's gzip format file.
- I expanded it with cpio command, but it includes too small number of files.
# file initramfs-3.10.0-121.el7.x86_64.img
initramfs-3.10.0-121.el7.x86_64.img: ASCII cpio archive (SVR4 with no CRC)
# cpio -idmv < initramfs-3.10.0-121.el7.x86_64.img

- Why doesn't it include a correct initramfs image data?
