In 45efa94 we introduced new mount options for the: 'aux', 'cfg', and
'var' partitions. To save boot time, we also disabled the periodic fsck
check, which does not affect journal replay or other Ext4 safety or
integrity checks. The latter involved calling tune2fs at runtime, but
this caused the following to appear for the 'aux' partition, which is an
ext2 for systems that need to change U-Boot settings, e.g., to set MAC
address on systems without a VPD.
EXT4-fs: Mount option(s) incompatible with ext2
To make matters worse, the new mount option(s), e.g., 'commit=30', gave
us another set of warnings from the kernel. This was due to the fstype
being 'auto', so the kernel objected to options not being applicable to
every filesystem it tried before ending up with extfs:
squashfs: Unknown parameter 'commit'
vfat: Unknown parameter 'commit'
exfat: Unknown parameter 'commit'
fuseblk: Unknown parameter 'commit'
btrfs: Unknown parameter 'errors'
This commit explicitly sets aux to ext2, and the others to ext4, and it
now checks before calling tune2fs that the partition/disk image is ext4.
