What group were you trying to add, and to which version of /etc/group? > So i'm guessing this only applies when u have chrooted "OS's" within > your OS? I'm guessing you're getting closer. When I want to add a group to the system, I usually specify the name of the new group on the command line: addgroup -gid 2045 newgroup adds the group name "newgroup" to the /etc/group file and the shadow file, performing some checking as it goes. You can do this by hand with the vigr command, as well, but you have to remember to type things in the same way in both the "visible" and the shadow group files. And there are other checks directly editing doesn't do. (You can be even more direct and use vi, but vigr does do some of the checking for you, and allows you to specify the shadow group file without knowing the name of the file.) In the example you show above, I'm guessing that the reason the system says you aren't able to lock the group file is that there is no group file (in the file specified as the chroot directory for the jail) to lock. Since your example shows you make the directory and then immediately try to add a group, it is apparent that a lot of the initialization that would have to be done first has not been done. man -k chroot and then man the manual entries listed to read more about setting up a jail. Check the references at the bottom of each man page. It may take an hour or two to figure out the difference between what you were trying to do and what the command was trying to do for you. On the other hand, it may be enough to know that the -R option is not necessary if you are not setting up a chroot jail. -- Joel Rees Be careful where you see conspiracy.
