growfs issue?

[Erik Moe]

I’ve written some scripts to build Freebsd images for a couple of ARM boards that I own, Rasperry Pi B and Banana Pi.  I’ve been setting growfs_enable=“YES” in my rc.conf.  I haven’t had any issues until I made a change to how I build the fstab. Originally I was hard coding device names:

/dev/mmcsd0s2a         /               ufs rw,noatime                  1 1
/dev/mmcsd0s1          /boot/msdos     msdosfs rw,noatime              0 0

But switch to using labels so as I added new boards my scripts would be more robust:

/dev/ufs/rootfs         /               ufs rw,noatime                  1 1
/dev/msdosfs/MSDOSBOOT  /boot/msdos     msdosfs rw,noatime              0 0

Since then I’ve had issues on first boot:

GEOM_PART: ufs/rootfs was automatically resized.
  Use `gpart commit ufs/rootfs` to save changes or `gpart undo ufs/rootfs` to revert them.

If I drop into single user mode and run "gpart commit ufs/rootfs” and reboot the system it comes up fine and the disk is resized:

Does this have something to do with the labels in the fstab?
