Description admin 2009-07-08 19:00:13 UTC 
I have this settings (machine booting over PXE->NFS)

a-ryabov# grep root /etc/rc.conf
# rootfs in read-only
root_rw_mount="NO"
a-ryabov#  

a-ryabov# grep "ro " /etc/fstab
192.168.130.254:/shares/tftp/7.2/gp     /               nfs     ro 0 0
a-ryabov# 

But, after boot:
a-ryabov# mount | grep tftp
192.168.130.254:/shares/tftp/7.2/gp on / (nfs)

When I using 4.11 - all be OK - root fs mounted read-only

How-To-Repeat: boot over LAN (using PXE)

hello, I submitted a new PR because this problem comes from a bug in the 
'mount' command, see PR bin/139651

with best regards,

State Changed
From-To: open->patched

I can reproduce this on 7.4-PRERELEASE but not on 9.0-CURRENT. I assume 
that this has been fixed in 9.0.
Comment 4 Ian Lepore freebsd_committer freebsd_triage 2018-07-04 22:25:06 UTC 
This appears to have been fixed in the 8.0 timeframe. Re-confirmed that it still works properly on 12-current.
