sort of. ISTR there are config option(s) to mount ext{2,3} using
ext4. On at least one of my machines I see two such messages, but
the first is for ext3 and the second for ext2 :
[ 1.765843] sd 0:0:0:0: [sda] Attached SCSI disk
[ 1.792078] EXT3-fs (sda6): error: couldn't mount because of unsupported
optional features (240)
[ 1.795575] EXT2-fs (sda6): error: couldn't mount because of unsupported
optional features (240)
[ 1.818698] EXT4-fs (sda6): mounted filesystem with ordered data mode. Opts:
(null)
[ 1.821899] VFS: Mounted root (ext4 filesystem) readonly on device 8:6.
I can't remember when this started, and google is useless (loads of
references to converting *to* ext4, or for an obsolete config
option), but at some time the ext4 driver became able to mount ext3
and ext2 - if those were enabled.
