to still be in /usr/src, but you might be able to use a varsym for 'sys'
e.g. /usr/src/sys.stable, /usr/src/sys.current would be real directories,
and /usr/src/sys would be a varsym.
Why don't you try it? Remember to enable varsym with
'sysctl vfs.varsym_enable = 1'.
varsyms still need some work. The most useful varsym is the process-local
varsym but the 'varsym' program can't set those since it would only set
the varsym for it's own pid, not for the shell that exec'd it. I've been
on the fence as to whether I should implement a varsym built-in to sh and
csh, or whether I should augment the varsym implementation to allow the
varsym program to set varsym's for its parent process (given suitable
