Porting plymouth

[sbell at tdt.com]

I do have "splash" on the kernel command line.
 
When I start plymouthd, I get the following on my console:
 

[main.c]                        initialize_environment:initializing minimal work environment

Do you have "splash" on the kernel command line? What do the debug messages say?
