Or, you might just try a write, to see if the fs is read-only or read-write:
====
Slackware 13.37
sl1337:/etc/rc.d/rc.S
==
Early in boot, & prior to any remount rw:
==
.
.
# Test to see if the root partition is read-only, like it ought to be.
READWRITE=no
if touch /fsrwtestfile 2>/dev/null; then
rm -f /fsrwtestfile
READWRITE=yes
else
echo "Testing root filesystem status: read-only filesystem"
fi
.
.
