Want to understand Buildroot - the 3 compression modes
I'm using buildroot to generate my images and for sure there is the option of compression with the help of different methods (LZO, LZMA, gzip, ...).
So far i found these 3 compression options in buildroot (v. 2013.11):
- Kernel compression Mode (in make linux-menuconfig)
- Built-in initramfs compression mode (in make linux-menuconfig)
- Compression method for the .cpio root filesystem ( (in make menuconfig)
my questions are:
1 ) what is the difference of these modes (like is just the kernel compressed? is the whole image at once compressed, and where are the pros and cons between these 3 mentioned modes) and
2 ) why am I forced to chose between 3 methods for the kernel compression, instead of leaving it uncompressed ?
