[HOWTO] Creating ZFS kernel modules for SystemRescueCD
Hi guys,
this article is WIP [work in progress/process]
since I don't have access to gmail via SystemRescueCD right now (midori keeps on crashing when trying to log in; the gmail draft functionality is quite handy sometimes),
I'm pasting the preliminary raw data here and will add more later to make more sense of it - for some of you it might already be enough
Kernel Configuration:
(currently for 4.5.1)
alternate kernel amd64 config:
http://pastebin.com/p9n2SdW8
3.18.5-alt451-amd64 x86_64
default kernel amd64 config:
http://pastebin.com/qCX0uc2c
3.14.31-std451-amd64 x86_64
fixme:
Remove the first line (zcat /proc/config.gz)
from the pasted kernel config file
Toolchain:
fixme:
BEFORE building kernel modules switch toolchain
ld.bfd
binutils 2.23.2
gcc 4.8.3
fixme:
AFTER building kernel modules switch toolchain
CFLAGS for kernel modules:
fixme:
BEFORE building kernel modules switch CFLAGS
for (almost) universal compatibility
| Code: | | -march=nocona -mtune=generic |
fixme:
AFTER building kernel modules switch CFLAGS
Build Tools:
bliss-initramfs 1.8.1 specifically is needed, since that version includes support for buildling the SRM kernel modules
https://github.com/kernelOfTruth/ZFS-for-SystemRescueCD/tree/ZFS-for-SysRescCD-4.3.0-r3/bliss-initramfs/1.8.1
SystemRescueCD USB-Stick Setup:
http://www.sysresccd.org/Sysresccd-manual-en_How_to_install_SystemRescueCd_on_an_USB-stick#E.29_Manual_installation_from_Linux_using_cp_.28deprecated.29
I prefer to follow the manual installation steps and learned to distrust scripts (latest example is Steam for Linux where moving it into a different directy deletes all your home directory content !)
in addition to step "Step 3: Copy files from the CD-ROM"
/mnt/usbstick/boot/grub/grub-451.cfg needs to be modified
to replace
and
with
and
Caching with Alternate Kernel, 64bit:
if you're lazy/productive like me and would like to have an option to pre-cache all files of SysRescueCD with the Alternate Kernel option,
you can add
| Code: | menuentry "SystemRescueCd (64bit, alternative kernel cache all files in memory)" {
set gfxpayload=keep
linux /syslinux/altker64 docache
initrd /syslinux/initram.igz
} |
to
/mnt/usbstick/boot/grub/grub-451.cfg
