[Kernel-packages] [Bug 2028568] Re: Ship kernel modules compressed
hi, i like portions of the patch, but not quite where in the machinery it is implemented. As we have many more packages that ship .ko modules, and those debs should not be compressed. And also i'd want to enable in-kernel decompressor too. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/2028568 Title: Ship kernel modules compressed Status in linux package in Ubuntu: New Bug description: To reduce the size of the initramfs and also to speed up the boot (by only decompressing the modules that are needed), please compress the kernel modules.
