It is easy as it says.
- As root
mkdir /usr/srcand then
chownit to a standard user
syssrc.tgzfrom the appropriate sources directory.
- Extract to root directory since the archive already contains the
tar -xzf syssrc.tgz -C /
The CONF file is self explanatory, I just commented out any lines mentioning
mpu (since that is where I was experiencing issues) and then added
options ACPI_BLACKLIST_YEAR=1 in to force it to load since I'd forgotten to update the BIOS.
There is no need for
build.sh (which is in src.tgz) if building for the same architecture, apparently.
Took quite some time on the brick, enough to cycle to the shops and mow a lawn, but it did build.
