After updating gentoo-sources to 2.6.20 and rebuilding kernel modules, I get the following error with unionfs 1.5_pre200701042308: * Determining the location of the kernel source code * Found kernel source directory: * /usr/src/linux * Found sources for kernel version: * 2.6.20-gentoo * * you need the proper kernel version! * * kernel: 2.4.x (x>19) Version: 1.0.14 * kernel: 2.6.x (x<9) Version: Not Supported * kernel: 2.6.9 - 2.6.15 Version: 1.1.5 * kernel: 2.6.16 Version: 1.2 * kernel: 2.6.17 Version: 1.3 * kernel: 2.6.18 Version: 1.4 * kernel: 2.6.19 Version: 1.5 !!! ERROR: sys-fs/unionfs-1.5_pre200701042308 failed. As with 2.6.19 there's no 1.5 release available yet. A compatible version would have to be either a 1.6 snapshot or 2.0 which does seem to be available, at least for -mm.

Created attachment 111364 [details] ebuild gzipped - untar to /usr/local/portage/sys-kernel/gentoo-sources contains a slightly modified ebuild based on gentoo-sources-2.6.20
Created attachment 111365 [details] patch - put to /usr/portage/distfiles Contains the unionfs diff from http://www.filesystems.org/project-unionfs.html
The attachments from comments #3 and #4 add the unionfs 2.0 diff as a patchset to gentoo-sources-2.6.20. For me it works. I use it for the squashed portage tree discribed on http://gentoo-wiki.com/HOWTO_VERY_small_Portage_Tree_with_SquashFS_and_UnionFS

This is a general problem, and shouldn't be tied specifically to the hp-cluster group.
We're in kind of a tough spot on this because they've started releasing unionfs as a 2.x series, which is a kernel patch rather than a standalone package. I'm requesting to the kernel team that they include the patch in gentoo-sources for 2.6.21 and newer.
Sorry, we aren't taking feature patches at the moment. If it were useful to a large number of people, or it were useful to release engineering, then we may consider it after it's merged into Linus' tree. Unless the newer versions of unionfs are hooking deeper into the kernel, it should be possible for you to separate the source files out and build it externally (like the older versions).
Is someone looking into building a unionfs-utils package? Now that its tied to the kernel very tightly (the patch modifies non-unionfs kernel headers) and the utils are in a separate package, it would require that we have a utils package.
