Normally, yes, it would only be good for kernel output, but as someone
else mentioned, you have livecd-functions.sh that re-writes the inittab.
Well, guess what triggers it? That's right, a "console=" option on the
command line. If you type (or via catalyst, add) console=something,
livecd-functions.sh (via functions.sh in baselayout) will interpret it
and modify inittab accordingly before we ever even hit runlevel 3, so it
starts a console on that serial line for login.
So I tried setting 'livecd/bootargs: console=ttyS0,115200' in
installcd-stage2-minimal.spec and indeed it does setup a tty on the
serial line. However, it doesn't actually seem to pass "bootargs" to
the kernel or there is some other wierdness going on as the dmesg
information AND all of the sysvinit output remains only on the vga
console. The last output on the fbconsole is some wierd error message
about bootsplash right before attaching a tty to the serial line. This
is an improvement for me but I would really like to see the kernel
output/etc. so I can see if the boot processes has hung.
You're positive that it's not being passed to the kernel? I'm pretty sure that
livecd-tools would read it from /proc/cmdline, which is the arguments passed to
the kernel. If it shows up in /proc/cmdline, then it's the kernel that isn't
honoring it, not catalyst/genkernel/isolinux that is doing something wrong.
I think it is an ordering issue, rather than it not being passed. I
just checked the code and the splash code appends to the very end of the
kernel command line, meaning it takes precedence.
I won't be able to test anything until Monday. Would an option to
completely disable the splash be reasonable?
That's what the -nofb kernel does. However, there isn't currently an option to
have a framebuffer without splash. I'm not sure if it would still pass the
splash options if you don't enable splash stuff in livecd-stage2.spec, but I bet
it would.
