- fix FS#56688

- empty passwd,gpasswd,group,gpasswd (need systemd >v235)

- package version bump to 4

pwck/grpck don't support comments in these files.
Thanks to grawity for reporting it.

- use uid/gid in PKGBUILD to avoid dependency to itself
- add nobody as a static user (FS#55589)
- add headers to passwd,shadow,group,gshadow
- sort deps and backup alphabetically

Glibc depends on filesystem, so it creates a depency loop.

- define archlinux default PATH with a systemd environment generator

- Implement /etc/profile check PATH (FS#47884)
- Move rfkill group to rfkill package
- Move locate to mlocate package (FS#53539)
- Remove systemd provided users and groups
- Move filesystem users/group to systemd-sysusers (FS#45196)
- Remove install scriptlet
- Remove nss compat from nsswitch.conf (FS#54592)
- Remove host.conf order (FS#54875)
- Remove end of file in config files
- Add headers and hint to man page for config files
- Remove archlinux man page. Wiki and install are far better.

- FS#52408

- fix FS#46694

- https://www.archlinux.org/todo/use-gpg-signatures-and-https-sources/
- support remote patch

- cleanup vars

- give more realistic examples in /etc/crypttab (FS#34452)

- sync group with gshadow (FS#40953)
- add input group

- add systemd-* users to stock shadow file (FS#40800)
- run pwdconv/grpconv if we touch passwd/group, respecitively (FS#40800)

- preemptively add systemd-network user/group

This removes redundant entires due to the newly introduced symlinks
and also reorders the entries to follow the system-wide PATH set by
systemd.
