lbu creates apkovl overlay file, but it doesn't apply on reboot.
Admittedly I am fairly new to linux in general and am using this for a very specified task so it's entirely possible I'm missing something obvious. I've learned a lot trying to get this to work, but please bear with me.
I'm running Alpine on a Raspberry Pi in Diskless mode. I've configured lbu_backupdir=/media/mmcblk0p1/media
and when I run lbu ci
I see that the apkovl is created in the target directory. I can extract the files from the apkovl and my changes are there, but when I reboot the pi, the overlay isn't applied.
It seems that I'm not the only person having this issue. Others have been discussing this for years. For instance: Another thread on reddit with the same issue
Maybe this is something that I'm fundamentally misunderstanding or the wiki isn't adequately explaining for someone who isn't a full-time linux guru, but I've been beating my head against it for three days and it feels like it just doesn't work.
Any help would be appreciated, thank you.
