This technique could be extended to the rest of the startup. Instead of
the dots, show a determinate progress bar (that is, one that fills up).
In addition, *if* the progress bar hasn’t moved at all in the past ~5
seconds, show the most recent startup message below it.
I would probably suggest showing the current SystemD target being
reached, or just having been reached.
In a sense you do not need the "show phases" thing to show technical
information other than what part of the boot process is happening. In a
sense, this is codified in the SystemD stages or targets such as the
SysInit target and the Cryptsetup target.
But the startup messages are not saved, this is a huge issue for
troubleshooting.
"Reached target Start Networking" ---<-- that is useful information.
KDE employs a 5-icon startup sequence or something like that. It is not
hugely informational but at least illustrative.
I would prefer a startup sequence with either 5 icons (5 is the best
number for this) or a progress bar, but both with text underneath such
as "Starting Networking" or at worst, but still at best, if nothing else
"Reached target XXX".
Checking filesystems
Starting networking
Mounting disks
Unlocking cryptography
Loading desktop
Those are candidates for "stages". They are also the most likely points
where something can hang.
