I didn't have it either; I installed it specifically to test this thing. Unfortunately, installing it also brought in "cryptsetup" and related packages, which modified the initrd images. Because of that, I don't recommend this test for anyone else. unicorn:~$ lsinitramfs -l /boot/initrd.img-5.10.0-8-amd64 | head drwxr-xr-x 2 root root 0 Apr 25 08:00 kernel drwxr-xr-x 2 root root 0 Apr 25 08:00 kernel/x86 drwxr-xr-x 2 root root 0 Apr 25 08:00 kernel/x86/microcode drwxr-xr-x 2 root root 0 Apr 25 08:00 kernel/x86/microcode/.enuineIntel.align.0123456789abc -rw-r--r-- 1 root root 4609024 Apr 25 08:00 kernel/x86/microcode/GenuineIntel.bin drwxr-xr-x 8 root root 0 Aug 2 07:24 . lrwxrwxrwx 1 root root 7 Aug 2 07:24 bin -> usr/bin drwxr-xr-x 3 root root 0 Aug 2 07:24 conf -rw-r--r-- 1 root root 16 Aug 2 07:24 conf/arch.conf drwxr-xr-x 2 root root 0 Aug 2 07:24 conf/conf.d unicorn:~$ lsinitrd /boot/initrd.img-5.10.0-8-amd64 | head Image: /boot/initrd.img-5.10.0-8-amd64: 39M ======================================================================== Early CPIO image ======================================================================== drwxr-xr-x 2 root root 0 Apr 25 08:00 kernel drwxr-xr-x 2 root root 0 Apr 25 08:00 kernel/x86 drwxr-xr-x 2 root root 0 Apr 25 08:00 kernel/x86/microcode drwxr-xr-x 2 root root 0 Apr 25 08:00 kernel/x86/microcode/.enuineIntel.align.0123456789abc -rw-r--r-- 1 root root 4609024 Apr 25 08:00 kernel/x86/microcode/GenuineIntel.bin ======================================================================== At first glance, it looks like the difference in line count might be due to these headers and footers around each archive. But if I actually do diff -u <(lsinitramfs -l /boot/initrd.img-5.10.0-8-amd64) <(lsinitrd /boot/initrd.img-5.10.0-8-amd64) | less there are a whole bunch of other differences. Some archive member files are moved around, which I cannot understand (the biggest offenders are the 0-length hard link indicators such as usr/bin/umount). I'm not sure if those are the *only* differences, because there's so much noise due to that.
