A centralized list for these renames is not good because:
- It breaks disabledModules for modules that have a rename defined
- Adding/removing renames for a module means having to find them in the
central file
- Merge conflicts due to multiple people editing the central file
In #68792 it was discovered that /dev/fuse doesn't have
wordl-read-writeable permissions anymore. The cause of this is that the
tmpfiles examples in systemd were reorganized and split into more files.
We thus lost some of the configuration we were depending on.
In this commit some of the new tmpfiles configuration that are
applicable to us are added which also makes wtmp/lastlog in the pam
module not necessary anymore.
Rationale for the new tmpfile configs:
- `journal-nowcow.conf`: Contains chattr +C for journald logs which
makes sense on copy-on-write filesystems like Btrfs. Other filesystems
shouldn't do anything funny when that flag is set.
- `static-nodes-permissions.conf`: Contains some permission overrides
for some device nodes like audio, loop, tun, fuse and kvm.
- `systemd-nspawn.conf`: Makes sure `/var/lib/machines` exists and old
snapshots are properly removed.
- `systemd-tmp.conf`: Removes systemd services related private tmp
folders and temporary coredump files.
- `var.conf`: Creates some useful directories in `/var` which we would
create anyway at some point. Also includes
`/var/log/{wtmp,btmp,lastlog}`.
Fixes #68792.
Having pam_unix set to "sufficient" means early-succeeding account
management group, as soon as pam_unix.so is succeeding.
This is not sufficient. For example, nixos modules might install nss
modules for user lookup, so pam_unix.so succeeds, and we end the stack
successfully, even though other pam account modules might want to do
more extensive checks.
Other distros seem to set pam_unix.so to 'required', so if there are
other pam modules in that management group, they get a chance to do some
validation too.
For SSSD, @PsyanticY already added a workaround knob in
https://github.com/NixOS/nixpkgs/pull/31969, while stating this should
be the default anyway.
I did some thinking in what could break - after this commit, we require
pam_unix to succeed, means we require `getent passwd $username` to
return something.
This is the case for all local users due to the passwd nss module, and
also the case for all modules installing their nss module to
nsswitch.conf - true for ldap (if not explicitly disabled) and sssd.
I'm not so sure about krb5, cc @eqyiel for opinions. Is there some nss
module loaded? Should the pam account module be placed before pam_unix?
We don't drop the `security.pam.services.<name?>.sssdStrictAccess`
option, as it's also used some lines below to tweak error behaviour
inside the pam sssd module itself (by changing it's 'control' field).
This is also required to get admin login for Google OS Login working
(#51566), as their pam_oslogin_admin accounts module takes care of sudo
configuration.
I think pam_lastlog is the only thing that writes to these files in
practice on a modern Linux system, so in a configuration that doesn't
use that module, we don't need to create these files.
I used tmpfiles.d instead of activation snippets to create the logs.
It's good enough for upstream and other distros; it's probably good
enough for us.

* orbment, velox: don't expose subprojects
the development of orbment and velox got stuck
their subprojects (bemenu, dmenu-wayland, st-wayland) don't work correctly outside of parent projects
so hide them to not confuse people
swc and wld libraries are unpopular and unlike wlc are not used by anything except velox

Looking at upstream git repo (git://github.com/Yubico/pam-u2f.git) the
docs initially said the path was ~/.yubico/u2f_keys, but it was later
changed to ~/.config/Yubico/u2f_keys (in 2015).
I have run pam_u2f.so with "debug" option and observed that the correct
path indeed is ~/.config/Yubico/u2f_keys.
Currently, ecryptfs support is coupled to `security.pam.enableEcryptfs`, but one
might want to use ecryptfs without enabling the PAM functionality. This commit
splits it out into a `boot.supportedFilesystems` switch.
