Bug 891625 – app-containers/lxd now requires ipv6

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Hervé Guillemet 2023-01-21 17:14:17 UTC]

Since 5.0.3, lxd package cannot build on a system without ipv6.
The use flag has been removed and is required from dependencies.
Any reason for that ? Could you reintroduce the use flag ?

Reproducible: Always

Steps to Reproduce:
USE=-ipv6 emerge -av lxd
Actual Results:  
The following USE changes are necessary to proceed:
 (see "package.use" in the portage(5) man page for more details)
# required by app-containers/lxd-5.0.1-r5::gentoo
# required by @selected
# required by @world (argument)
>=net-dns/dnsmasq-2.86-r1 ipv6


Expected Results:  
Build without ipv6 support

    app-containers/lxd: enhance openrc init.d file
    
     - attempt to only create /sys/fs/cgroup/systemd if rc.conf has support for it,
     - enhance the pkg_postinst messages,
     - remove 'ipv6' use flag as the dependencies already enable it by default.

I could've sworn I didn't see ipv6 use flag in dnsmasq anymore, but indeed it's there. Yeah lxd itself doesn't have a toggleable option for ipv6, it was just to make sure ALL the deps have it built-in. And as you can see, ipv6 is slowly being unconditionally enabled throughout the tree.

But I can fix this for now indeed.
