I only recieved one reply on this subject, from Darren Dunham, which I've

I have decided not to patch the Solaris 2.5.1 machines in question, since we
want to try to upgrade everything to Solaris 8 soon anyways.

Thanks for your help!


Darren Dunham:
If you have 'patchadd' (which is in Solaris 2.6 and up I believe) this
is mentioned in the man page for it..


     To successfully install a  patch  to  a  client  or  server,
     patchadd  must  be issued twice, once with the -R option and
     once with the -S option. This guarantees that the  patch  is
     installed  to  both  the  /usr  and root partitions. This is
     necessary if there are both /usr and root  packages  in  the

The -S option lets you apply the patch on the server just to the
exported /usr for the clients.

You'd have to investigate the patchadd script options for the patch
you're interested in applying.  It may support the same options.

Original Post

I have to patch a few Solaris 2.5.1 systems that have / and var mounted from
local disks, and /usr (and everything else) nfs mounted from remote machines.
Has anyone ever patched systems setup like this before?  How does it handle
the files that are supposed to be installed in /usr?  Can you still patch the
kernel and files in /?

Here's an example of the df output.
 df -k
