| |
Hi All, I've been struggling trying to find the cause of a regression in 30-rc1 (compared to 2.6.29) where I am no longer able to make-install a kernel via an NFS mounted home directory.
Historically I do all of my kernel development/building on one machine and then I have a bunch of test machines that are NIS/NFS clients of that machine that have the same /home mounted. When I am ready to deploy a kernel, I log into that machine and su to root to simply "make modules_install && make install" the kernel. This has always worked until recently. I started getting this message:
INSTALL sound/usb/caiaq/snd-usb-caiaq.ko INSTALL sound/usb/snd-usb-audio.ko INSTALL sound/usb/snd-usb-lib.ko INSTALL sound/usb/usx2y/snd-usb-usx2y.ko DEPMOD 2.6.30-rc1-vbus rm: cannot remove `include/config/kernel.release': Permission denied make: *** [include/config/kernel.release] Error 1
I understand what is going on w.r.t. the root shell having permisssion problems modifying data on an NFS mount. However, this _used_ to work so I started investigating for what I thought would be a minor change to kbuild that I could patch. At first I simply just hacked the makefile to make the kernel.release stuff use the "-" to ignore the error. This did manage to get me past the initial problem, but then I immediately ran into more problems related to the generation of version.h and version.h.tmp as well.
Looking into this, I couldnt track down where the "filechk" magic was coming from (any hints from the kbuild gurus?). So I thought that I would try to bisect the issue. However, that failed to produce a bad commit for reasons that I do not quite understand either. Here is the git-bisect log:

What I dont really understand is that this (I thought) was supposed to look for where the behavior first appeared between v2.6.29..HEAD, but some points along the way were actually before v2.6.29 was cut. I don't really know what went wrong, but if it matters I am running git 1.6.2.
At this point, I am stuck. Perhaps there is a better methodology to deploying the kernels that I should employ, but I am not sure which to use yet. Any help appreciated!
