Bug#928096: systemd does not play well with nfs root - unable to shutdown/reboot
Package: live-build
Version: 1:20190311
Severity: normal
Hi, I'm playing with images using nfs root, my host is debian sid amd64,
I build images for buster amd64
I'm using qemu:
kvm \
-m 2048 \
-vga qxl \
-serial stdio \
-usb -device usb-tablet \
-soundhw hda \
-netdev user,id=net0,host=192.168.76.1,net=192.168.76.0/24,dhcpstart=192.168.76.9 \
-device e1000,netdev=net0 \
-drive file=disk.img,if=ide,format=qcow2 \
-kernel binary/live/vmlinuz \
-initrd binary/live/initrd.img \
-append "boot=live persistence components netboot=nfs locales=it_IT.UTF-8 nfsroot=192.168.76.1:/home/sherpya/live-default/binary console=ttyS0,115200 console=tty"
/etc/exports:
/home/sherpya/live-default/binary *(ro,async,no_root_squash,no_subtree_check,insecure)
The system works fine but I'm unable to shutdown or reboot:
[ OK ] Reached target Reboot.

In a previous build (some days ago) it was working.
I have the same problem using files from debian live iso
I suppose the system cannot shutdown ethernet if the root is on nfs, and nfs live mount cannot
be unmounted.
I've seen around someone suggesting to make systemd ignore interface shutdown problems
