Re: Raspberry pi 3: btrfs as root fs and uboot (or grub?)

[Tom Callaway <tcallawa@xxxxxxxxxx>]

The pi firmware needs to be read off a fat partition:

Hi,

Current rawhide fedora image is using xfs has a bit higher memory requirements than btrfs so I've started thinking about migration of my current image to new root fs on new card.

Looking on partition table on rawhide image served by fedora I see:

Device         Boot   Start      End  Sectors  Size Id Type

/dev/mmcblk0p1         2048    61439    59392   29M  c W95 FAT32 (LBA)

/dev/mmcblk0p2 *      61440  1060863   999424  488M 83 Linux

/dev/mmcblk0p3      1060864  2060287   999424  488M 82 Linux swap / Solaris

/dev/mmcblk0p4      2060288 15126527 13066240  6.2G 82 Linux swap / Solaris

Q1: for what is this fat32 first partition?

Q2: is it possible to install uboot files from /boot on btrfs? (on x86 and grub it is no problem with this)

Q3: seems someone done porting of the grub to arm so why there is n grub2 package in fedora?
