good point, but look, nothing is static in solaris10

Code:

root@mp-wst01 # ldd /sbin/su.static
        libcmd.so.1 =>   /lib/libcmd.so.1
        libbsm.so.1 =>   /lib/libbsm.so.1
        libc.so.1 =>     /lib/libc.so.1
        libsocket.so.1 =>        /lib/libsocket.so.1
        libnsl.so.1 =>   /lib/libnsl.so.1
        libmd5.so.1 =>   /lib/libmd5.so.1
        libsecdb.so.1 =>         /lib/libsecdb.so.1
        libmp.so.2 =>    /lib/libmp.so.2
        libscf.so.1 =>   /lib/libscf.so.1

        libuutil.so.1 =>         /lib/libuutil.so.1

        libc.so.1 =>     /lib/libc.so.1

it's the same binary as well. sun recommends to include the /usr in the root filesystem. Sun EIS (Enterprise Installation Standards) follows the doctrine of Adrian Cockroft in his book "Solaris Performance and Tuning" ie "all in one slice". In particular sun does not have separate slices for /usr, /opt or even /usr/openwin! There may be reasons to have /var in a separate slice on a server (such as constraining the system from filling up with historic log and message files), which i always do and recommend...

if you have an own /usr, you could copy the shell to e.g. /sbin, links go to /lib in root and not to /usr/lib, that should do the job..

but anyhow, true, there is no explanation why, in a case of emergency it would be better to have a "not linked" shell
