I use LibreELEC on a RP3 B+ with TVHeadend. I have 2 USB drives for recordings. Normally my 128GB Flash drive gets mounted as /var/media/
sda1-usb-SanDisk_Ultra_Fi. I have TVH setup to put the recordings there. I also have a USB external hard drive and it normally comes up as /var/media/
sdb1-ata-TOSHIBA_HDWD120_. It has miscellaneous media files.
Occasionally, when I reboot the RP3 the drives comes up switched.
sda1-ata-TOSHIBA_HDWD120_
sdb1-usb-SanDisk_Ultra_Fi
This messes up the recording settings. Is there a way to force this like /etc/fstab?? I notice there isn't one on LibreELEC 9.01
