If you start to install SR10 from scratch from cartridge tape onto your newly invol-ed disk using the recommended new installation procedures (minst, install++), you may end up with a very undesired situation. Be warned. If you specify a 'closed' system, you end up with a system as open as possible, with acl-s allowing full access to the world. If you desire bsd-type inheritance rules (owner from process, group from directory), you won't get it. Both owner and group come from the process. (This looks like sys5 inheritance, apart from the non-organization inheritance). If you specify bsd as your primary environment, the /etc/environ file will contain ENVIRONMENT=sysv To get a closed system, specify as target machine not the usual "//nodename" but instead "//nodename/topdirectory", and move everything by hand back to the //nodename directory. However, the installation procedure still leaves many files with world access in the new system tree. You can trace them with appropriate variants of the command 'find /topdirectory -perm -002 -ls' and fix them by hand. This is terrible.
