You may have noticed some "Wait statements" appearing
during the boot process, and seen them in the scripts of
the boot sequence.
These seem rather adhoc and amateurish with comments like
"better wait a bit for slow spin-up devices".
My theory as to why this 'guess how long to wait' method is
not needed once the booting is done, is that THEN the OS
which is multitasking, has a proper method of attending to
MULTIPLE devices, which require various random times to
deliver their requests.
Is this correct ?
I came to thinking about this because it seems inconsistent that
the error mesg of my initrd, on a Compact Flash says <put the dir
to an IDE device because this can't read SCSI>.
Well if all the stuff up to there INCLUDING the very test and error
message could be read from the CF, why can't the rest be read
from the CF?
What do you say?
== TIA.

Not a whole lot since Mandriva/redhat have moved to systemd for system

boot.
Since you have posted the same question to redhat, mandriva,
slackware, debian,....
you apparently have no clue as to what distribution you are running.
Once you figure that out, please post to the appropriate newsgroup.

NO. My question is applicable to ALL computing.

And I want to discourage the childish-football-tribalism mentallity,

Note that different capabilities are involved in different stages
of the process. Reading a disk or other storage device address
raw is quite different from reading the same address location via
a device driver and software that can deal with the nature of the
file system.
No cheers your ignorance and arrogance merit this reply.

You're asking about waits in the initrd for some version of slackware.

Those waits are not present in a current Mandriva or Mageia distro,
so the question is not applicable to ALL computing.
It is only applicable to whatever distros still have those waits.
