Arch Linux

Description:
Running `mkinitcpio` with identical input, results in a different output byte steam each and every run. Comparing the initramfs .img files with `cmp` shows already a different after the 4th byte.

The root cause might need to be fixed in `cpio`.

Guess: different inode numbers (char c_ino[8]; in cpio_newc_header) on every run.

[code]
struct cpio_newc_header {
char c_magic[6];
char c_ino[8];
char c_mode[8];
char c_uid[8];
char c_gid[8];
char c_nlink[8];
char c_mtime[8];
char c_filesize[8];
char c_devmajor[8];
char c_devminor[8];
char c_rdevmajor[8];
char c_rdevminor[8];
char c_namesize[8];
char c_check[8];
};
[/code]

Steps to reproduce:
$ mkinitcpio -P
$ cp initramfs-linux.img{,~}
$ mkinitcpio -P
$ cmp -l /boot/initramfs-linux.img /boot/initramfs-linux.img~
