I have no problems running Debian with a f2fs root (on a Raspberry Pi,
to be precise).

If this is a question of fsck.f2fs not supporting the same options as
other fsck implementations, IMHO that should be fixed upstream instead
of adding a workaround in Debian with a wrapper script.

I already had this problem on raspbian wheezy as well and have it now on an
arm based NAS.  However, this might be a sysv-init only problem.  I did not
try to use systemd.

Its not! Like in xfs it is not possible to check a ro mounted f2fs filesystem.
fsck.f2fs does have the correct options, but is just telling the caller that
checking a mounted filesystem is unsupported with f2fs.

Touching /fastboot will work BTW because it will skip the failing call to
fsck.f2fs.

Hello,

at least when using System-V Init Debian is currently not able to run from
a f2fs root. The reason is, that fsck.f2fs is unable to check a ro mounted fs.

As this is also the case with xfs there is an easy solution:

1. Rename fsck.f2fs to something else like f2fs_repair or f2fs_check.

2. Copy fsck.xfs script to fsck.f2fs or replace with a slightly modified Version
  (e.g. printing F2FS instead of xfs).
