Guy, I've just finished installing the S/390 version of wheezy/sid into a Hercules emulator (the one from the Xubuntu repositories, seems to work fine).
Everything is working including networking, but to my dismay I noticed there's no DECNET support compiled into the kernel (yes, I am that nuts, I want DECNET on an S/390).
Anyway, so I downloaded kernel sources for linux-126.96.36.199 (188.8.131.52 seemed the closest to 2.6.32-45, which was shipped with the distro) from kernel.org and did a make menuconfig. All went swimmingly.
I am now running the proper "make" to build the kernel, and it seems to be working fine, too.
Now to my question: How do I _install_ this kernel, ideally as a new boot option when I IPL the box.
I assume I have to:
1. Generate a new initramdisk
2. Put the kernel somewhere
3. Put the new modules somewhere
4. Modify the bootloader
Now it's been a LONG time since I've done this (think slackware with lilo and kernel 1.x) so I have no idea how to proceed, especially on an S/390.
Anyone got any pointers?
As for my current setup, here's some data:
#cat uname -a:
Linux version 2.6.32-5-s390x (Debian 2.6.32-45) (firstname.lastname@example.org) (gcc version 4.3.5 (Debian 4.3.5-4) ) #1 SMP Sun May 6 03:12:45 UTC 2012
# cat /proc/version
Linux version 3.2.0-23-generic (buildd@crested) (gcc version 4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu4) ) #36-Ubuntu SMP Tue Apr 10 20:39:51 UTC 2012
PS: In the future, could you guys maybe include DECNET support in the mainstream kernel releases? Or is this a problem?
