adds gzip support if kernel modules are compressed by gzip
Last modified: 2008-02-11 20:17:09 EST
Description of problem: one (like IPCop and www.efw.it) like to compress the kernel modules to save space. this patch decompresses the modules during installing them in the initrd, if the kernel modules are gzip'd. previously i would like to copy them as they are and put gzip on the initrd, but that is not possibly because it is not static linked. Version-Release number of selected component (if applicable): 4.1.18 How reproducible: Steps to Reproduce: 1. 2. 3. Actual results: Expected results: Additional info: patch was needed for www.efw.it rc6 and has been developed by www.endian.it
