Re: [Libguestfs] [PATCH 3/3] febootstrap/helper: Major change to kernel module handling code

The previous implementation had two problems: (I) Not all needed kernel modules were copied to the initrd. (II) If a kernel module depended on more than one other module, only the first dependency was considered for the load order. Using 2.6.39-1-amd64 (Debian/unstable) ext2.ko was not loaded and therefore the root FS could not be mounted. The use of tsort(1) has been replaced with a set of functions that build a DAG in memory and use that to calculate the list of modules to be copied into the initrd and the order in which to laod them.
