One of them is in this > thread. Some server BMCs do have a serial port emulation which can be reached via s= sh (apart from IPMI, etc...). HPE's particular implementaion has it's escape character bound to the Escape key. So with plymouth running, i.e. because y= our boot hangs, which for me working on block, scsi and friends happens at least onc= e a week results in physically power cycling the machine as I can't exit the serial emulation and go back to the BMCs shell. I don't care too much as I'm just a developer and used to power cycle test machines, but I do care about the customer experience in this case. To me it looks like the plymouth folks have a slight disconnect from the server, or non-desktop world. We've already experienced this pattern in the world of init systems.
