Does anyone have a suggestion on how to debug this?
AFAIK PAM is used for logging in. However what you describe doesn't
make
sense to me.
I recall you can make PAM print or log messages.
However maybe its faster to try chrooting eg from a live cd and try
passwd or such setting a passowrd and examining the user's shell
setting.
This is a good suggestion, I'll try doing it. When chrooting, do I need
to run any activation script or so to set the Nix environment paths?
You didn't mention your way of installation.
I installed with the ordinary installation cd, but instead of mounting
a plain partition on /mnt, I mounted an NFS share. Also I disabled Grub
since I boot with gPXE:
boot.loader.grub.enable = true;
boot.loader.grub.device = "nodev";
I also have the following in configuration.nix in order to set up the
network on boot:
boot.initrd.extraUtilsCommands =
''
cp ${pkgs.iproute}/sbin/ip $out/bin
cp ${pkgs.glibc}/lib/libresolv.so.* $out/lib
cp ${pkgs.nfsUtils}/sbin/mount.nfs $out/bin
cp ${pkgs.klibc}/lib/klibc/bin.static/nfsmount $out/bin
'';
boot.initrd.postDeviceCommands =
''
ip link set eth0 up
ip addr add 192.168.0.200/24 dev eth0
'';
However, I haven't got the NFS mount to work automatically yet. Instead
I have:
mountPoint = "/";
fsType = "none";
device = "none";
And then I mount the root manually with "nfsmount
192.168.0.1:/export/nixos_root /mnt-root" when init stage 1 complains
that it can't mount the root device.
You can even try start ttyX from chroot after stopping tty from the
live
cd.
Thanks for the tip.
Why are you using NFS? I never tried booting from NFS. I think it
should
not make a difference. Do you mount rw or ro?
Maybe that also makes a difference (guessing)
I know that login writes to the disk keeping the last login
timestamp.
I am using NFS because my computer is a diskless one. I'm trying to
replicate my current ArchLinux setup which is gPXE for loading the
kernel and initrd over http, and NFS for mounting the root and other
filesystems. I mount the root rw, I have not separated /var, /usr etc
(yet).
