Description:
I would like to request that CONFIG_VGACON_SOFT_SCROLLBACK be turned on in the kernel config. This would enable one to use the variable VGACON_SOFT_SCROLLBACK_SIZE to set the buffer size of the tty.

I am pretty sure that Red Hat Enterprise Linux (and CentOS) set this to the following in their default kernel configuration:
CONFIG_VGACON_SOFT_SCROLLBACK=y
CONFIG_VGACON_SOFT_SCROLLBACK_SIZE=64

This is really not a priority request whatsoever. So please feel free to ignore this as long as you need if there are other more pressing packaging issues to address.

I also don't know if Archlinux chooses not to enable such options for any reasons either. So if this has been discussed in the past, please feel free to ignore this request.

Tobias and Thomas,

I would like to reiterate that although it would be nice to have this request addressed, I really feel as though you linux{,-headers,-docs} package maintainers should focus their efforts elsewhere if even slightly necessary. I really appreciate all the work that goes in to making this distribution excellent, and I know that it is a very small, but talented, team of folks to make Archlinux. As such, I will not be offended nor saddened if this request goes unanswered or gets shot down without comment (though if there is technical reason not to implement, it would be interesting to know).

Thanks for all you do!
