Hi Shashi, Have you read Nik's manual on "Making the World" your own at http://www.nothing-going-on.demon.co.uk/FreeBSD/make-world/make-world.html I went through the transition from 3.1-release to 3.1-stable, which eventually became 3.2-beta, 3.2-release and then 3.2-stable. I sometimes have trouble reading e-mail by glossing over things but from where I sit you aren't finishing the job before you reboot. The sequence to build a new world as I see it is as follows: 1- Cvsup the current 3.2-stable. 2- Read about "-DWANT_AOUT" because the aout files are no longer created by default. If you have a.out programs, you will probably have to create the aout files. Then, you can make the world. I prefer a buildworld followed by an installworld. I time the buildworld. 3- You have to update /etc, /dev, ... There are massive changes here from 2.2.8 > 3.2 that have to be addressed. The manual process in Nik's manual can be replaced by using "mergemaster". 4- You have to check GENERIC and LINT because these files will be changed and you will have to redo your specific changes. Then, you configure, build, and install your kernel. You may have to add "compat22" and I have seen this being discussed but I don't remember where. I don't have it in my kernel. 5- Somewhere in here you need to install new bootblocks. They changed after 2.2.8 and you have to update them. The floppy upgrade does this for you. 6- Now I think you can reboot. I did a floppy boot and used it to upgrade to 3.1. The aout_to_elf thing was done for me. I made a massive mistake at this point and cvsup'ed to current and 4.0-current had problems on my system. I probably should rephrase that and say I had problems with 4.0-current on my system. Mergemaster would have probably worked me through this block but I didn't know about it at the time. I ended up reinstalling 3.1-release from the CDROM. I basically do my 6 steps everytime I cvsup and build a new 3.x-stable. There are somethings such as step 5 that you can leave out but that depends on what you see get changed in the cvsup. It was taking 3+ hours to do the make world and 4 to 5 hours or more to make the other changes in Nik's manual. Mergemaster does a side-by-side and you choose what you want to merge. It tries to change all of the text files in /etc. That includes the host and passwd files. My system wasn't fully functional by the time I got to 3.2-beta and they had built 3.2-release before I really figured out what was going on. I didn't know what was broken. Just that it was broken. It was around a week after 3.2-release was made that 3.2-stable was upgraded and I had a fully functional system on my computer. Making the changes manually is just too slow and mergemaster is a wonderful tool. I eventually decided that the problems I was having were hardware. I have upgraded the system from a P166 Pentium to a Slot 1 motherboard. I currently have a Celeron 433 in it and a buildworld currently takes 40 minutes and the total job seems like 1.5 hours from start to finish. When I add creating the aout files, that will probably increase to around 2 wallclock hours. The new system provides me with more available time and I can get into trouble doing other things. The problem is remembering what you did wrong when you do your next build. I do keep some notes. I have an active link to Dan's diary in NZ land. I think everyone goes through the same painfull steps. It is nice to read these stories because you know you aren't the only one having fun <grin>.
