Nothing to do with my job or anything of the sort.
It is just a hobiit, I have been compiling and maintain my own linux stuff for
as long as the site LFS started (about 22 years).
With gcc-2.7.x and libc5, you can compile the whole distro in an hour,
Nowadays, it take me 24 hours on a 4 cores machine.
I can't remember exactly which version of glibc or linux started requiring -O2
So I ended compiling the whole thing in -O2,
otherwise they would simply refuse to compile.
It is still the same with the linux kernel. (I've just tried it)
Just to be rebelious and fun, I manage to compile the whole thing except
the kernel and bootloader (syslinux still requires at least -O1).
Anyway, Thanks for listening to a old man's ramblings.
