If you load them manually, which should not be necessary you have to load modules in the correct order

should filesystems-4.19.10-tinycore64.tcz be loaded before brtfs-progs.tcz  ?

Hi mocore
I would think  filesystems-4.19.10-tinycore64.tcz  should be listed in the dependency file since it contains the  btrfs.ko.gz  driver.
As a dependency it would be loaded first since dependencies are resolved and loaded before the extension that requires them
is loaded.

Please add raid-dm-KERNEL.tcz to btrfs-progs.tcz.dep - now (Core 13.1) btrfs.ko also depends on raid6_pq.ko.

@Juanito

Could you also add this to the current filesystems-* modules? (My particular case is 16.x x86_64)

It looks like it only ever got added to x86_64 for 13.x
(https://mirrors.dotsrc.org/tinycorelinux/13.x/x86_64/tcz/filesystems-5.15.10-tinycore64.tcz.dep)

I've checked the x86 and x86_64 ones after then and none of them appear to have raid-dm-KERNEL.tcz listed.

Hi mjmouse
Confirmed. I checked in several TC versions x86 and x86_64 and
btrfs.ko.gz depends on raid6_pq.ko.gz.

Updated .dep files for TC14, 15, 16, and 17 both x86 and x86_64.
