I don't know what you mean by "jail.con", But I have reviewed sysutils/jail2 which tries to work with the new /ect/jail.conf file and the jail(8) program. Whats provided with the new handbook jail chapter surpasses what it does in my opinion. > > related to this: > During the development of the jail.conf file method documented here, a > few bugs came to light with the jail(8) program which the author has > fixed, but which are not included in the 9.1-RELEASE.

There are no pr's on the bugs I have been working with Jamia Gritton on. He's the author of the jail(8) program. I don't see the need to list them here. But I can say downloading the jail(8) source and doing a make on it this morning has resolved many problems I was experiencing. One of the problems was fixed in the kernel source so downloading a fresh copy and recompiling your kernel will put you ahead of my testing bed. hahaha > > also any idea/example of how to use the cpuset.id would be appreciated. As I read it, processes running on the host pretty much share all the cpu's across all tasks as they call for service. cupset is all ready available at the host level if I remember correctly. cpuset.id provides a way to give a jail a larger slice of the time slice resources at a cpu level. In simple terms make that jail run faster. On the other side of that same coin it could be used to limit what the jail would normally be getting. All depends how you code the parameter and how many jail definitions it's used in. You may want to give this a try, it's already in 9.1 http://forums.freebsd.org/showthread.php?t=28871 Let me know if you have any success using it on jails. Also if you have time, download those handbook scripts and play around and see it you like what they build for you. > > regards > >
