[Bug 425650] Re: Karmic: Re-generation of grub.cfg takes long time.

[moma]

Re-hello,

Ok, new updates just arrived with os-prober v1.31 package.

a) First, upgrading an existing system. Here is the message log after running
$ sudo aptitude update && sudo aptitude upgrade

...

(hd1)	/dev/sdb

Now the GRUB2 update took only a few seconds (maybe 5 - 6 seconds or
so).

But some menu entries are missing.
The newly-generated /boot/grub/grub.cfg file contains only entries from this actual Ubuntu installation + rescue mode and memtest86.  It does not include the various Linuxes from other partitions.  Most notably the "Other operating systems:" section of grub.cfg is completly empty.  See the attached grub.cfg.

The version of os-prober is now:

$ sudo apt-cache show os-prober

b) I also did a totally new 64bit Ubuntu Alpha5 installation.
The grub.cfg after first boot is exactly 100% same as in the upgrade step a).

And files in /etc/grub.d/ are:
$ ls -l /etc/grub.d/
-rwxr-xr-x 1 root root 2944 2009-09-01 23:53 00_header
-rwxr-xr-x 1 root root 1154 2009-09-01 23:41 05_debian_theme
-rwxr-xr-x 1 root root 3434 2009-09-01 23:53 10_linux
-rwxr-xr-x 1 root root  472 2009-06-24 18:04 20_memtest86+
-rwxr-xr-x 1 root root 5123 2009-09-01 23:53 30_os-prober
-rwxr-xr-x 1 root root   84 2009-09-01 23:53 40_custom
-rw-r--r-- 1 root root  483 2009-09-01 23:53 README
--------

The missing menu entries (the other partitions/Linuces) are not a big
problem because I always maintain my own grub.cfg manually.

But maybe the "30_otheros" script is still required?  Or maybe 30_os-
prober script needs som fine-tuning?

See the attached grub.cfg.

Do not hesitate to ask me to do additional tests. I'll very happy to help. That's what I do.
