One side-effect of symlinking kernel configs to watch out for:  If you
happen to 'make buildkernel' on one machine, then try to 'make
installkernel' on another, with /usr/src mounted over NFS, the kernel
config still has to be accessible to the installing machine - which may or
may not work, depending where your symlink points to.  I'm not sure if this
is also the case for the standalone kernel build process using config(8).

I worked around this by keeping the configs in /usr/src/sys/i386/conf, but
making sure that directory was included in my daily backups.
