# e2fsck /dev/sda1
e2fsck 1.42.5 (29-Jul-2012)
ext2fs_check_if_mount: Can’t check if filesystem is mounted due to missing mtab file while determining whether /dev/sda1 is mounted.
e2fsck: e2fsck not compiled with HTREE support,

      but filesystem /dev/sda1 has HTREE directories.

e2fsck: Get a newer version of e2fsck!

/dev/sda1: WARNING: Filesystem still has errors

Possible solution –enable-htree in e2fsprogs configure

Review all our source tree so that if one tries to use MAKEFLAGS should not fail.

Right now would have to set those parts that need to be forced to -j1.

udev needs at least kernel version 2.6.27 (specified in the README file provided at sources).
There are some error messages while booting 2.7-test1:

error getting socket: invalid argument
initiaizing netlink socket error
udevadm [382]: error sending message: Connection refued.

Then devices nodes aren't created and we got this too:
fsck.ext2: No such file or directory while trying to open /dev/mmcblk0p2
