Yes it is.  I've done a number of release builds on my -stable box and
CVSROOT/val-tags hasn't been touched in ages even though my locally
mounted /home/ncvs is mounted read-write.  I also did a -current 'make
release' on another box that has the /home/ncvs NFS mounted.  I think it
might be mounted read-write, but root gets turned into nobody who does't
have write access.  I know that is true because 'cvs update' without the
-R option barfs because it lacks write permission.

Interesting ...  'cvs -R' shouldn't be trying to write anything in
/home/ncvs.  Also, if /home/ncvs is actually mounted read-only, it looks
to me like write attempts should return an EROFS error instead of EPERM.
