Did you not finish reading my posting?? I mentioned that 'init' needed to be fixed, and even gave the output from 'df' I think any Sun admin who saw you running with / and /usr in the same partition would die laughing. It's exactly because the default setup has / and /usr in the same partition that I nearly THREW UP and I sat down and fixed that IMMEDIATELY. there are many more changes which are necessary to move stuff from /bin into /usr/bin, and make it 'stick' properly. I believe I made it quite clear in my previous posting that / and /usr are in seperate postings. I copied all the binaries that I absolutely needed into /sbin. That is essentially what Sun did as well. I know what is going on. A sun machine needs / and /usr both to run single user. It does mount /usr as read-only, but it needs some of the binaries there. They place only about 6 programs in /sbin (hostname, ifconfig, init, mount, sh, and one called intr). I found that I needed a bunch more in /sbin -- every program that /etc/rc ever needs. And, I had to modify init.c so that init would know to look for sh and fsck in /sbin instead of /bin. Really, it is working, and you can tell because my root partition is using LESS than 15M of disk while my /usr is enormous.
