Precisely as expected!  Which part of "use with the default boot option, but
not with the alternatives" is unclear :-)  Sorry, it's actually a pretty
common mistake.

If you want an option available to both the default and alternate boot
stanzas, you put it in the "kopt" variable.

Yeah...  but don't ask me what the difference is :-)

My _bet_ (and I could tell for sure if I saw your boot process) is that it's
in the Network initialization.   The splash intentionally times out if it
doesn't get an [OK] response in a given time - otherwise you could sit
watching the splash forever.  My network startup waits for 30 (or maybe 60)
seconds if it isn't connected (presumably a dhcp timeout - it's not
something I care about as I almost never reboot) and the splash screen goes
away.

Just use ctrl-alt-f8, and it puts you back to the terminal where the boot
process was logging.  Interestingly, when doing this to find out which
terminal it was on, I discovered one of _my_ last scripts (S99nxserver) has
an error, and _it_ is working fine, too!
