I'm also not super convinced we need to support all those compression options, but we already have plenty of them, and Peter is just adding one more, which doesn't make the whole thing much more complicated. We can continue the discussion on whether we want to keep this or not, especially in light of http://patchwork.ozlabs.org/patch/850055/ that proposes to allow compressing the sdcard.img generated by genimage. If we allow compression rootfs.tar, why not sdcard.img ? Best regards, Thomas -- Thomas Petazzoni, CTO, Free Electrons Embedded Linux, Kernel and Android engineering http://free-electrons.com
