unmkinitramfs is normally used on initrds that were created with mkinitramfs. unmkinitramfs will be able to decompress the initrd created by mkinitramfs (unless the used compressor is removed in between).
The compression can be configured by the user and is zstd by default currently. initramfs-tools-core recommends zstd. Should it suggest lz4 and the other compressors? ** Changed in: initramfs-tools (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1971430 Title: lz4 is not a dependency of initramfs-tools-core To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/initramfs-tools/+bug/1971430/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
