USE=sysv-utils seems to just be to use systemd halt/poweroff etc |
| 34 |
binaries/symlinks, instead of sysvinit. It also happens to provide a |
| 35 |
/sbin/init symlink, as otherwise none would exist (as with that USE, |
| 36 |
sysvinit is blocked from being installed). All the documentation says |
| 37 |
to set init kernel command line, or use dracut, with which systemd |
| 38 |
already starts on its own or something. E.g, |
| 39 |
https://wiki.gentoo.org/wiki/Systemd#GRUB_2 |
| 40 |
|
| 41 |
If for docker you need something else, you can consider migrating the |
| 42 |
images to USE=sysvinit, which can be troublesome if you need to keep |
| 43 |
openrc for dependency resolution (I believe the work towards gentoo- |
| 44 |
functions for non-openrc gentoo stuff is ongoing and hopefully soon |
| 45 |
fully finished), or maybe you use dracut there too as initramfs, so it |
| 46 |
presumably wouldn't matter, if that doc is right? |
| 47 |
Or there's something to improve in packages for this use case, but this |
| 48 |
might be easier once gentoo-functions is fully baked.. |
