[Ubifs] Reboot -> "recovery needed"?

[Gilles]

Hello

	The root filesystem lives in a partition on a NAND, and I noticed
that after running "reboot", at the next boot, I get this message:

===============
...
UBIFS: recovery needed
UBIFS: recovery completed
UBIFS: mounted UBI device 0, volume 0, name "rootfs"
UBIFS: file system size:   251596800 bytes (245700 KiB, 239 MiB, 1950
LEBs)
UBIFS: journal size:       9033728 bytes (8822 KiB, 8 MiB, 71 LEBs)
UBIFS: media format:       w4/r0 (latest is w4/r0)
UBIFS: default compressor: lzo
UBIFS: reserved for root:  0 bytes (0 KiB)
VFS: Mounted root (ubifs filesystem) on device 0:10.
===============

Is this the way Ubifs works, or should I run a command prior to
"reboot"?

Thank you.
