Hello,
I am trying to optimize boot up time for my board.
I ran bootchart and observed that virtual console devices are being created
in very high number which finally cause the boot up time to increase by 1.5
seconds.
I have been researching as to where these are actually being created and
have failed to find anything concrete.Is there some way to reduce the
count of virtual devices on the kernel side?
Regards,
Tushar

It is userspace that is creating these consoles, so fix up your
userspace code and all should be good.
