# Tips for the maintainer (i.e.: future me?):
#
#  - I check in the .SRCINFO file because it makes it easier to verify
#    that the metadata changes are what you expect.
#  - I use the `./srcinfo.sh` script to update .SRCINFO after
#    `libremakepkg`ing the package.

# There are a lot of pkgnames in this file, whether in the pkgname=()
# array, or in provides=(), conflicts=(), or replaces=().  Let's go
# over where each comes from and what it means, for clarity.
#
# Inherited from Arch:
#  * systemd's current pkgname=():
#    - `systemd`: Duh
#    - `systemd-libs`: `libsystemd.so`, `libudev.so`, and the NSS modules
#    - `systemd-resolvconf`: resolvconf(1)
#    - `systemd-sysvcompat`: init(1), halt(8), poweroff(8), reboot(8), shutdown(8)
#    - `systemd-ukify`: ukify(1)
#  * historical systemd pkgname=() values:
#    - `udev`: existed as a split package 2012-02 to 2012-05, when it merged into
#      `systemd-tools`
#    - `systemd-tools`: existed as a split package 2012-02 to 2012-08, when it
#      merged into `systemd`
#    - `libsystemd`: the name of `systemd-libs` prior to 2019-02
#  * separate packages:
#    - `systemd-sysvcompat`: existed as a separate package (not a split package)
#      2012-02 to 2012-06
#    - `nss-myhostname`: a separate that existed first in `extra` then in `core`,
#      2012-02 to 2013-01, when it became part of systemd
#    - `sysvinit`: a separate package that existed in `core` until 2013-05
#    - `openresolv`: prior to 2018-06 this was Arch's only `resolvconf`
#      implementation, so most packages depended on it instead of the `resolvconf`
#      virtual package
#  * virtual packages:
#    - `resolvconf`: since 2018-06, resolvconf(1)
#
# From Parabola (mostly by the decision-making of lukeshu):
#  * systemd's current pkgname=():
#    - We further split `systemd` into:
#       + `systemd`: systemd itself
#       + `systemd-udev`: just udev
#       + `systemd-common`: files shared between `systemd` and `systemd-udev`
#    - We further split `systemd-libs` into a separate package for each
#      library and NSS module:
#       + `systemd-libsystemd`
#       + `systemd-libudev`
#       + `systemd-nss-systemd`
#       + `systemd-nss-myhostname`
#       + `systemd-nss-mymachines`
#       + `systemd-nss-resolve`
#      Separating libsystemd and libudev are obvious.  I can make a good case for
#      separating nss-myhostname, because it's useful on nonsystemd boxes.  But I
#      guess I (lukeshu) separated out the other NSS modules too just for
#      consistency with nss-myhostname?  I'm sure I felt strongly about it at the
#      time.
#  * separate packages:
#    - `notsystemd-resolvconf`: existed 2018-07 to 2018-08, was identical to
#      `systemd-resolvconf`
#  * virtual packages:
#    - `init`: `/usr/bin/init`; invented by lukeshu in order to have mutual
#      provides/conflicts between `systemd-sysvcompat`, `sysvinit`, and
#      `openrc-init`.
#    - `libsystemd-standalone`: `libsystemd.so`; the pkgname has `-standalone`
#      appended because we inherited from Arch a different (historical) meaning of
#      what the `libsystemd` pkgname is.
#    - `libudev`: `libudev.so`
#    - `nss-systemd`: `libnss_systemd.so`
#    - `nss-myhostname`: `libnss_myhostname.so`
#    - `nss-mymachines`: `libnss_mymachines.so`
#    - `nss-resolve`: `libnss_resolve.so`
