complete in src tree build world w/o /usr/include/** ?
Hi, I once again ran into the problem that a buildworld didn't succeed as unpriv. user without populating some headers to the base system before. But I do not want to populate headers that do not match my installed system on that machine if I am building for another one. This leads to inconsistency. Is there any chance that the whole source tree could be built w/o /usr/include/** ? or should that be the case already ? or why can't it be done ? -- Greetings Bjoern A.

FreeBSD Live Upgrade best practice?
Hi, I'd like to try some sort of Live Upgrade. Given: -STABLE box with an extra disk. Intended procedure: - Install 5.2.1-RELEASE (given it works on that box) on the extra disk - Adapt configuration from -STABLE - shutdown - change -STABLE disk with 5.2.1 disk - boot and run 5.2.1 - optionally update to 5-CURRENT Is this a feasable procedure? How would I best install the 5.2.1 on the extra disk. I thought I'd just extract the -release tarballs using the install.sh script? However there is also mtree information, and of course the extra disk is not mounted on / but on /mnt What do I else need to think of? I know that I probably cannot create UFS2 filesystems with the -stable system. But I guess I can run UFS(1) as well until I move each filesystem to UFS2 using the (now spare) old -stable system disk. Maybe someone has already done such a thing?

Using Kernel level mutex in FreeBSD 4.8
Hi, I am trying to use kernle level mutex in my driver for FreeBSD 4.8. I tried searching for kernel level mutex but couldn't find any information on the same. The kernel level mutex functions mtx_lock(..), mutex(..), mtx_init(..) and other mtx_ functions are available from FreeBSD 5.0 onwards and not in FreeBSD 4.8. Kindly adavice me how should i proceed. Also is there anything like Gaint lock in FreeBSD 4.8. If so then how can i use it. Any early reply will be of great help. Thanks in advance Jitendra - Do you Yahoo!? Yahoo!

off topic - disk crash
Today an important (no backup of course) 46 GB IBM Deskstar IDE disk crashed. It has a FreeBSD 4.8 on it with important data and programs. Yes, shame on me that I didn't care about doing backups on it but it has happened. I evend tend to expend the bucks to get it recovered but a little prediagnosis I would not to be left untried. The disk boots into FreeBSD but already at power on time the disk does seek retries or some recalibration noise. The question is what else can I do to recover the data. Put it in the icebox? Turn the computer upside down? Any ideas would be welcome. I thought of getting a second identical disk to exchange electronics only but since it partially functions it looks more like surface corruption, doesn't it? -- Chris Christoph P. U.

Re: off topic - disk crash
You could also use dd with the bs/count operands to skip the bad blocks, but this will probably be much more frustrating that the conv operand. Another option (that is slower than dd but less stressful on the failing drive) I've used are the dump/restore utilities. I have the specific commands for Solaris, but the process should work for FreeBSD with some alterations (I can email it to you off list if you would like). This is the general procedure I use for the dump/restore utilities: 1. Attach second ide drive to cable/controller, same size or larger than the failing disk. This will be your recovery disk. 2. Boot from CD into single user mode (for freebsd check out www.freesbie.org site and/or use the port). 3. Format, partition, label (make sure it is bootable), and create the new file system on the recovery disk so it is identical to the old disk. 4. Fsck the new and failing disks. 5. Setup and verify your swap partition on the recovery disk. 6. Mount the recovery disk partition. 7. Dump/restore the old disk partition to the new disk partition. Repeat 6/7 for each partition. 8. Mount the failing disk partitions and compare to the recovery disk for consistency. 9. Unmount all disk partitions. 10. Shutdown the system, remove the failing drive/CD, power it back up, and test. -Marcus - Marcus Beaman Data Network Operations Analyst DAS/IRMD/ENS NOC 503-378-3627 - ---REPLY--- Date: Thu, 11 Mar 2004 15:21:28 +0100 From: Daniel Lang [EMAIL PROTECTED] To: C.

Re: make install (kernel) without /modules dir
I forget to say that this problem is for 4. branch

Hi,
It seems that I've found another problem. If /modules dir would be
removed,
make install (of kernel and kernel modules) will not create modules
dir and you'll
get /modules file with one of the modules inside.
One of the variants is to add flag -d to install or other to mkdir -p

inetd needs discard service in /etc/services
While updating my diskless setup, I was trying to determine the minimal set of entries required in /etc/services in addition to a NIS + line to get a system to boot cleanly. I discovered that inetd depends on the existence of the discard service. The dependency is due to the fact that getaddrinfo is used to generate sockaddr_in(6) struct's and it's not really up to the task when we know neither the hostname or the service name. For some reason, discard was picked when IPv6 support was added and it's remained ever sense. A better organization of the code could work around this problem one of several ways, but that's more work then I want to do at this time. There also appears to be a secondary bug, probably in getaddrinfo that means that even though we can look discard up in NIS when inetd is started, it isn't being resolved there by getaddrinfo. I would like to commit the following patch. It changes the port from discard to syslog and documents the dependency. I choose syslog because it really does need to be in /etc/services on most machines since it starts before NIS. I'll also file a PR against inetd in hopes that someone gets board enough to fix it some day.

RE: Intel i8xx watchdog driver
I would love to incorporate it in both source trees if possible. Before it goes into current, I need to make some changes so that it will work with Poul-Henning Kamp's new watchdog driver model. Hopefully, I'll get to work on that some tomorrow. I'll release a new version for current as soon as it's ready. -- Daryl -Original Message- From: Mike Tancsa [mailto:[EMAIL PROTECTED] Sent: Wednesday, March 10, 2004 9:17 PM To: Wm.

diff included in commit mail
Hi, I know it was discussed once somewhere, but I can't find the thread in question. What I would like to be able to do is see the actual commit included in the mail. I know it can't be done at the moment the message arrives, as that is before it arrives in my cvs tree. On my machine I have the cvs repo mirrored, so doing it in realtime is no problem. Does anybody have scripts or whatever available to do this?

RE: Intel i8xx watchdog driver
Thanks, thats great news. Perhaps even as a port would do the trick. ---Mike At 08:07 PM 11/03/2004, Wm. Daryl Hawkins wrote: I would love to incorporate it in both source trees if possible.
