Some server BMCs do have a serial port emulation which can be reached via ssh
(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 your boot
hangs, which for me working on block, scsi and friends happens at least once 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.
