From: Christian Hesse <mail(a)eworm.de> Having files on btrfs subvolumes requires to give mount options. Add boot params archisoflags= and cow_flags= for this purpose. Boot parameters could look like this: ... archisodevice=/dev/sdaX archisoflags=subvolume=isos cow_device=/dev/sdaX cow_flags=subvolume=persist ...

Hi, Recent builds of archsio only have 256Mb of availble space, it used to be 32G under img. Is there a way to either enlarge overlay size (other than cow_spacesize cheat code)? Some installation of extra tools via pacman fail due to no free space on drive.... Mr Green
