I do have /var/empty, but not until mountcritlocal. profile runs
dhclient before I have /var/empty. Since the cost of putting the
/var/empty in the /var directory (not yet a mountpoint) costs 1 inode
and nothing more. It is, of course, hidden when the var partition is
mounted with the "real" /var/empty directory.

I should have clarified this.

 I use the ISC dhclient, but it is not available when profile.sh runs
 (before mountcritlocal), so the dhclient used by profile is the default
 one.

I could install ISC dhclient in /sbin, but I try not to muck with /sbin
unless I REALLY have to so so.
