Not a single user can log in on my system

[leyvi]

Not technically a kernel issue, but definately a system one:
Checked permissions for login shells, all good.
Nothing in syslog. Started in the middle of my last update: after I locked the screen (I use KDE) I couldn't unlock, and trying to log in from a VT would tell me that the user did not exist (for every single one).
If you're wondering how I got the logs, I used the livecd.
Get this weird thing printed when I open a new tmux pane after chrooting into my system:

UPDATE:
In rc.log was a whole bunch of errors about different systemd modules missing symbol definitions. Not good.
I use OpenRC, but there are a few services that depend on systemd.
I noticed during my last update that the strip command kept failing at the end of each emerge, something to do with object files not being formatted correctly. Maybe there's a connection? Tried oneshotting all the relevant systemd-related packages, failed due to an undefined symbol named crypt_r.

without any error or log files it is hardly possible to provide you any good solution.

So here is just a wild guess:
Maybe something failed during the last update? Power outage? Disk failure?
It sounds like something is really off.

I think the best way, if possible, to boot from a USB stick and chroot into it.

As mentioned, I did try chrooting into my system from livecd. I didn't find much. Tried emerge oneshotting some stuff that looked sus. I will use wgetpaste to upload my entire log directory for analysis as soon as I get home.

Should I try updating my @world from inside the chroot?

Also, the one thing I did find in my logs were a lot of errors related to undefined symbols, missing functionality, and during my last update strip kept failing, something about invalid file formats.

leyvi,

Has your console keymap got (re)set?

[leyvi]

Thanks for the suggestion, Ned. I'll look into it as soon as I get home.
I don't think that's the issue though. My OS (without the LiveCD) boots fine, with a few systemd-related services failing. When I type any of my usersnames into the login prompt, they come out the way I'd expect (typing "root" yields "root"), just login doesn't like them.

leyvi,

Is PAM if you use it, in a mess?

Keymaps cam be quite subtle.
us and gb are very similar, with a few keys swapped. Usernames are OK. Passwords may not be, if you use one or more of the swapped symbols.

No, I don't use PAM. Perhaps the issue is related to all the errors to do with symbols mentioned previously? You'll definately see them, once I upload the log directory.

Also: if I wgetpaste a tarball, would that be convenient for you guys? I can provide a PGP signature as well, if you like.

leyvi,

Play with the -s and -S options to wgetpaste. Different sites have different size limits.
Downloading things makes us all nervous.

Try to boot in to single user to example rootfs. May be rootfs was corrupted or bad storage.

I just got home:
File: /etc/conf.d/keymaps
