After trying several times. I just do the following steps:
- Rune 0.4_20170229, run on RPI3
#4434
- Extend patition
- Update kernel by hondagx35's guide:
#4434391
- Edit /etc/rc.local to fix sched_rr_timeslice_ms = 10 (Same as before update):
nano /etc/rc.local
Add to:
#!/bin/sh
echo 10 > /proc/sys/kernel/sched_rr_timeslice_ms
chmod +x /etc/rc.local
nano /usr/lib/systemd/system/rc-local.service
Edit:
[Unit]
Description=fix kernel optimizations
After=network.target
[Service]
Type=simple
ExecStart=/etc/rc.local
TimeoutSec=0
[Install]
WantedBy=multi-user.target
systemctl enable rc-local
systemctl start rc-local
After that it's work fine on RPi3 B+!
Thanks again PierreG64.

PS: i use Apple TC as NAS for music storage. After update, on RuneUI album cover artwork is not displayed. After work around, at last it's OK with SMB advanced options:
