Source: u-boot Package: u-boot-sunxi Version: 2021.01+dfsg-5 Severity: wishlist
Hi, the current u-boot-packages (at least up to 2021.07+dfsg-1 in experimental) lack btrfs support which makes it impossible to boot from a btrfs partition – even though u-boot itself has btrfs support, it's just not enabled in Debian's packages. Please consider enabling btrfs support via the options CONFIG_FS_BTRFS=y and CONFIG_CMD_BTRFS=y. I have tested these options with local builds of u-boot-sunxi on two of my Allwinner A20 based single board computers for about half a year now (on top of 2021.01+dfsg-5 as well as 2021.07+dfsg-1) and it works well. It allows me to boot from a single btrfs root partition without the need for a separate boot partition which is useful for example if you use btrfs snapshots so the root filesystem and the boot files are in sync when you boot an older snapshot. Thanks! Timo
