In the version 2.20 mingetty features have been merged to agetty, now, by default, screen is cleaned before prompting for the login name. As the cleaning process remove most of openrc's output (shift+pageup show only part of boot runlevel in my case, nothing more). Any debug what failed while booting is much harder and I thing this is enough reason to change /etc/inittab (which is sysvinit file) and add '--noclear' switch to agetty in order to restore non-cleaning behavior. Reproducible: Always
CC'in base-system as in metadata.xml.
Tested just now with sys-apps/util-linux-2.20. Adding --noclear in inittab keeps the terminal history stay intact.
sounds like work. if you dont like the new behavior, then you can use --noclear. or convince upstream to make --noclear the default.
Vapier, terribly bad that you do not see improvements here. You blindly follow upstream even when, like in this case, the clear-by-default behavior destroy last lines of backlog, making them unreadable so you have to use --noclear or enable logging in rc.conf if you want see what failing on start. I'm disappointed.
The change in default behaviour is annoying, mainly because there is no indication of why the screen is now clearing. Sticking with upstream default is fine by me, but an explanation/warning in the elog would be nice.
that is a perfectly reasonable request. should be all set now in the tree; thanks for the tip! Commit message: Inform users of new default clear behavior http://sources.gentoo.org/sys-apps/util-linux/util-linux-2.20-r1.ebuild?r1=1.1&r2=1.2 http://sources.gentoo.org/sys-apps/util-linux/util-linux-9999.ebuild?r1=1.24&r2=1.25
That's better, but it is not clear where the option should be inserted. How about this? The agetty util now defaults to clearing the terminal before showing the login prompt. To restore the old behaviour, edit /etc/inittab to add the --noclear option by changing c1:12345:respawn:/sbin/agetty 38400 tty1 linux to c1:12345:respawn:/sbin/agetty --noclear 38400 tty1 linux
Created attachment 294553 [details, diff] Patch for the last comment. Here's the patch to implement Comment #7, patching 2.20-r1 and 2.20.1. I understand the column width should be < 80, and I've actually tried $ ebuild <ebuild> postinst. Thanks all.
