Hi I upgraded from jaunty 64 bit server to karmic 64 bit server and the upgrade was pretty smooth with few glitces The console was not working since ttyS0 was defined in /etc/event.d and that no longer works per <a href="http://www.ubuntu.com/getubuntu/releasenotes/910">http://www.ubuntu.com/getubuntu/releasenotes/910</a> So I made changes as explained here <a href="https://help.ubuntu.com/community/SerialConsoleHowto">https://help.ubuntu.com/community/SerialConsoleHowto</a> and now console looks lot better. I also had to remove the splash and quiet again since they reappeared in /boot/grub/menu.lst file. Needed to run update-grub afterwords. Now the problem is how do I create a /boot/grub/grub.cfg file from scratch? the upgrade did not create one. Also there is no /etc/default/grub file. I guess I can create one like the one in <a href="https://help.ubuntu.com/community/SerialConsoleHowto">https://help.ubuntu.com/community/SerialConsoleHowto</a> And I like to migrate to ext4 as well So all in all, I am looking for ext3 to ext4 upgrade and grub migration procedure from 9.04 to 9.10. So the upgrade procedure for ubuntu server as shown here <a href="http://www.ubuntu.com/getubuntu/upgrading">http://www.ubuntu.com/getubuntu/upgrading</a> should really need more than those three steps to cover the ext3 to ext4 and grub upgrade procedure The release notes only said "Switching to ext4 requires manually updating grub" with a link to ext4 wiki. But no clear steps there. I really appreciate if someone either provide some steps here or update the content on one of the above links I discussed above Thanks -- Asif Iqbal PGP Key: 0xE62693C5 KeyServer: <a href="http://pgp.mit.edu">pgp.mit.edu</a> A: Because it messes up the order in which people normally read text.
