Additional hooks may look for other environment variables and should be documented by the help output for the hook. +Reproducibility +--------------- +mkinitcpio aims to create reproducible initramfs images by default. + +This means that two subsequent runs of mkinitcpio should produce two files +that are identical at the binary level. + +Timestamps within the initramfs are set to the Unix epoch of 1970-01-01. + +Note that in order for the build to be fully reproducible, the compressor +specified (e.g. gzip, xz) must also produce reproducible archives. At the time +of writing, as an inexhaustive example, the lzop compressor is incapable of +producing reproducible archives due to the insertion of a runtime timestamp. + +More information can be found at https://reproducible-builds.org. + Files ----- '/etc/mkinitcpio.conf':: |
