There is little point in moving the utilities for the dynamically linked case, since they are small in that case. Just don't put their libraries in the root partition, so that they work like mount_smbfs does now (not, if /usr is not mounted). mount_smbfs isn't actually dynamically linked currently: %%% $ file /sbin/mount_smbfs /sbin/mount_smbfs: ELF 32-bit LSB executable, Intel 80386, version 1 (FreeBSD), for FreeBSD 5.0, statically linked, stripped %%% The world was built with NOSHARED=yes. This seems to be a bug in mount_smbfs/Makefile: %%% # Needs to be dynamically linked for optional dlopen() access to # userland libiconv (see the -E option). # NOSHARED?= NO %%% If it really needs to be dynamically linked, then NOSHARED should be set unconditionally. BTW, rc.ng still doesn't support nfs-mounting /usr. It attempts to use utilities in /usr before /usr is mounted. From console.log: %%% ...
