I mount all my "root" filesystems (SYSPLEX, VERSION, & SYSTEM) as READ, along with the "product" filesystems as well. If I really need to do an update, I use a UNIX shell and "cd" to the proper subdirectory. Then do a "chmount -w .". Update the filesystem (update a file or rmdir or mkdir, whatever). Then "chmount -r ." again. My .profile adds /usr/sbin to my PATH, which makes using chmount easier. -- John McKown Systems Engineer IV IT Administrative Services Group HealthMarkets(r) 9151 Boulevard 26 * N.
