Gleb,

Unfortunatly not. Two important differences:

- This is about fsck, not mount, and if you happen to have /usr on an
ext2 because you're sharing storage with Linux, you've sawed off the
very branch on which you were sitting.  We don't have a mountprog=...
equivalent for fsck anyways according to fstab(5)/mount(8) in FreeBSD 12.1.

- FreeBSD has a native r/w capable ext2fs ext2/3/4 driver, which doesn't
do journalling though, so we need to have fsck available. The kernel
cannot possibly recover a dirty FS - that would require journalling.

(We also have two fuse-based user-space implementations, one ships as
FUSEFS option in e2fsprogs, but is slow, so its disabled by default, and
sysutils/fusefs-ext2, https://github.com/alperakcan/fuse-ext2 which
looks to be in early development and is mostly in Git, the last release
from Git was two years ago.)

Cheers,
Matthias
