Also from man hier:
/compat/ normally a link to /usr/compat. If not, then the /usr/comp=
at
comments apply (created by sysinstall(8))
...
/usr/compat/ files needed to support binary compatibility with
other operating systems, such as Linux (created b=
y
sysinstall(8))
So, I think the installer should be rather fixed to created this paths
as it was before.
Also, linux_base ports as well as ports .mk files reference /compat/linux
e.g. as default LINUXBASE.
