Some time ago I felt the need to update the Ubuntu distro as you did.
After the 10.04 Karmic upgrade I got two major issues:
A boot issue with Plymouth. I found a quick workaround by removing the plymouth config files in /etc.
A Syslog issue , where rsyslogd is running 100% CPU.
First issue came back when I did upgrade to 11.04: every first boot stops due to the plymoth bug. when I reboot It runs fine.
To handle the second issue I have to update the colinux kernel or to get back to syslog 4.2.0-2ubuntu8
Currently I just disable syslog by executing "Service rsyslog stop" after logging.
I would appreciate your help on the way you handled this two points.
Thanks in advance,
The document directory of the distribution lists what I did to fix the plymouth problems:
- Fixed Plymouth aborts by mounting /dev as tmpfs in fstab
- Fixed missing console output and gnome panel with disabled shutdown button by
disabling plymouth*.conf files.
The plymouth files were renamed to disable them.
Add to fstab:
dev /dev tmpfs rw 0 0
I found these solutions using google search.
I don't recall any problems related to syslog.
It probably is a good idea to upgrade to the latest stable version of colinux when you are upgrading Ubuntu. I would also note that if colinux kernel version is not the same or higher that the kernel version of stock Ubuntu then it may not work with having some problem(s)
Sorry for the plymouth point, I think I read your doc a bit too quickly.
Dealing with Syslog, I found this post relating my issue:
I upgraded to the 0.7.9 Colinux version before doing the Ubuntu upgrade.
uname -a gives me the following:
Linux colinux 22.214.171.124-co-0.7.9 #1 PREEMPT Sat Apr 9 20:30:51 UTC 2011 i686 i686 i386 GNU/Linux
The post I refer to suggest I have to upgrade my kernel or downgrade syslog. I was wondering if you had rebuild any colinux kernel to manage this issue.
Thanks for your feedback.
By the way, I did apply all the solutions you suggest for the plymouth point. It worked fine until I upgraded once more. Now my system boots fine the second try, systematically. I hoped you had a more robust solution.
