It may have only missed by a few Bytes.

On my 5.2.1 system (and it was probably the same on 4.7) the default
is to build new kernel modules after backing up the old ones in the
/boot/kernel.old directory.  So try:

du -hc /boot/kernel

To see how many blocks are used there.  Add that to the size of the
compiled kernel (when you've retrieved some space) and it's probably
close to 25% of 129MByte.  Close enough to believe the error message.

Only you would know, presuming you're the only user with 'root' access.
You have /var and /tmp on different partitions so no problem there.

There should be no need to.

>what should I do?

Find which process or user is abusing the root file system
and make it stop, and then move or delete the errant files.
I'd guess you've been filling /root so try:

du -hc /root

<advice>
You should only ask technical questions at questions at freebsd.org
As a newbie, which is mostly who you'll find on a newbie list, I
could be dangerously wrong.  Could've been a simple typo which
if commanded by the super user would have erased a crucial part
of the file system.  Such an error would be spotted by other
subscribers, to the questions@ list, who quickly respond with
corrections.  There are times when the newbie@ list is so quiet
that there may not be any "peer review".
Not good for quality technical questions and answers.

Be 'root' as rarely as possible.
