[gentoo-dev] Global Systemd USE Flag

["Jason A. Donenfeld" <Jason@zx2c4.com>]

Hi,

Sorry if this has been discussed to death, but I couldn't find any
definitive decisions on it, so I thought I'd mention things in a
fairly simple manner:

Step 1: I use OpenRC/sysvinit.

Dell ~ # readlink -f /proc/1/exe
/sbin/init
Dell ~ # equery b /sbin/init
 * Searching for /sbin/init ...
sys-apps/sysvinit-2.88-r3 (/sbin/init)


Step 2: There are lots of systemd service files installed.

Dell ~ # ls /usr/lib/systemd/system/*.service|wc -l
21


Step 3: What on earth is installing them?

Dell ~ # equery b /usr/lib/systemd/system/*.service
media-libs/libcanberra-0.29
(/usr/lib/systemd/system/canberra-system-shutdown-reboot.service)
media-libs/libcanberra-0.29
(/usr/lib/systemd/system/canberra-system-bootup.service)
media-libs/libcanberra-0.29
(/usr/lib/systemd/system/canberra-system-shutdown.service)
media-sound/alsa-utils-1.0.25-r2 (/usr/lib/systemd/system/alsa-restore.service)
media-sound/alsa-utils-1.0.25-r2 (/usr/lib/systemd/system/alsa-store.service)
net-misc/dhcpcd-5.5.6 (/usr/lib/systemd/system/dhcpcd.service)

net-misc/openssh-6.0_p1-r1 (/usr/lib/systemd/system/sshd.service)
net-wireless/bluez-4.101-r1 (/usr/lib/systemd/system/bluetooth.service)
net-wireless/wpa_supplicant-1.0 (/usr/lib/systemd/system/wpa_supplicant.service)

sys-power/upower-0.9.17-r1 (/usr/lib/systemd/system/upower.service)


Yowza! All the packages that provide systemd unit files are installing
them?! But I don't even use systemd. I don't want this cruft on my
system.

Proposal: global USE flag for systemd, just like there's one for openrc.


Thanks,
Jason
