XZ
configname: CONFIG_INITRAMFS_COMPRESSION_XZ
Built-in initramfs compression mode
└─>XZ
In linux kernel since version 2.6.38 (release Date: 2011-03-14)
XZ uses the LZMA2 algorithm and has a large dictionary which may cause
problems on memory constrained systems. The initramfs size is about
30% smaller with XZ in comparison to gzip. Decompression speed is
better than that of bzip2 but worse than gzip and LZO. Compression is
slow.
If you choose this, keep in mind that you may need to install the xz
tool to be able to compress the initram.
