Not right now. jdk14 is the newest supported by the Nixpkgs version on
which the current SDE package is based. Lifting it to a newer Nixpkgs
version will be non-trivial. I don't want to do that for now unless
it's really necessary.

Ok, I'll drop the "con".

This depends on the platform. On the WEDGE systems, ttyS0 is connected
to the BMC and the speed is 57600 by default. I use this to set the
"console" kernel parameter and the GRUB serial setting to work
correctly via the BMC SOL.  Changing the speed here would interfere
with that, I guess, so I need to be careful.

How are the serial ports set up on the 2556? Is there a similiar setup
with a BMC and one of these serial ports?  The WEDGEs also have a
physical serial port configured as 9600 8N1 by default that is
connected to the BMC.

I'm a bit reluctant to do this since the serial port is the last
resort for accessing the device. I suppose this can somehow co-exist
with the regular agetty process on /dev/ttyS0 that allows access to
the host system, but how can it be guaranteed that it will fall back
to a normal login shell if anything goes wrong with freerouter or this
"intercept" process?

Right. The profile should have been spelled with a "_",
i.e. NOP_MCHOME. With the hyphen, the builder generated the wrong
preprocessor symbol PROFILE_NOP-MCHOME and so the profile was never
actually activated.  This is fixed in
