How to create a 2nd loopback interface lo:1
Hello
I need to create a 2nd loopback interface lo:1.
This command is doing the job
ip addr add 192.168.100.0/32 dev lo
But I want it persistent even after a reboot.
On debian-like distro I just need to populate
/etc/network/interfaces
But on arch it does not exist.
How to proceed ?

Re: How to create a 2nd loopback interface lo:1
Generically eg. using systemd service - or any other script that runs during the system start, preferably invoked early by your network managing service.
If you're using systemd-networkd, https://man.archlinux.org/man/systemd.netdev.5

But if you unconditionally need the interface, just add it w/ a systemd service.

Re: How to create a 2nd loopback interface lo:1
Thanks, it works with.
cat /etc/systemd/system/2ndloopback.service
[Unit]
Description=create 2nd loopback service 192.168.100.1 to bind transmission on it
[Service]
User=root
WorkingDirectory=/root
ExecStart=/bin/bash -c '/usr/bin/ip addr add 192.168.100.1/32 dev lo'
[Install]
WantedBy=multi-user.target
I do not know if other options would be better.
