If by soft link you mean symbolic link, I would not do that, some packages remove the symlink and create a new directory. Use a loopback mount instead (man lofs). We still have /usr/local for historical reasons (software compiled over the last 15+ years that still works thanks to Solaris binary compatibility) but it is a read-only NFS mount so technically it is separate from /usr.

Anyone who still uses sunfreeware.com is truly desperate or clueless : > Ouch that hurt. Also, soft links dont always work - but I cannot think of a way to fool a mount point. Patches dont add a significant amount of space to anything else but /var and, any half way near competent computer person would have measures in place to keep track of disk space usage anyway so having a separate / and /usr seems more trouble than its worth. In fact the whole idea of using a tiny disk, ancient OS release, no RAM, whatever it takes to save a few precious watts, etc is wonky from the start : > Doable but seems like a wasted effort with little payoff. All this ranting sorry. But when OpenSolaris first came out I built it from the then available source and tried to make a "full" install as small as possible. After a LOT of effort I could easily fit everything on a CD. This was before X was part of the picture. Point is you can make Solaris 11 SMALL if you really want to. Same goes for update 5 of Solaris 10 where you can pick and choose if you are careful what packages you want to install.

Which is one reason why I recommend Blastwave over Sun Freeware. -- Rich Teer, SCSA, SCNA, SCSECA CEO, My Online Home Inventory URLs: http://www.rite-group.com/rich http://www.linkedin.com/in/richteer http://www.myonlinehomeinventory.com

By partitioning your disk that way. No "tricking" required; you can manually create your partitions and designate what they hold as you like. I will say that if you want to save space, you may want to fold /usr into /; there's not much point in separating them unless you're trying to keep /usr read-only. On the other hand, to you really want /home (or /export/home, whichever you're using) to be part of /? > > For info: my current install of Solaris 7 is on a 9GB disk: > $ uname -a > SunOS kingdom 5.7 Generic_106541-08 sun4m sparc SUNW,SPARCstation-5 > $ df -k > Filesystem kbytes used avail capacity Mounted on > /proc 0 0 0 0% /proc > /dev/dsk/c0t3d0s0 30399 17377 9983 64% / > /dev/dsk/c0t3d0s6 8358189 4386164 3888444 54% /usr > fd 0 0 0 0% /dev/fd > /dev/dsk/c0t3d0s1 62407 20086 36081 36% /var > swap 285172 1044 284128 1% /tmp > > /opt sits in /usr here.

That's not a reason to separate /usr, which does not generally change. In fact, /usr changes so seldom that the only good reason to separate /usr is if you're going to make it read-only, which you can do in a well-regulated system. -- Christopher Mattern NOTICE Thank you for noticing this new notice Your noticing it has been noted And will be reported to the authorities |
