Description Silviu Marin-Caea 2008-10-02 13:31:57 UTC 
I have done an upgrade to factory from beta1, and I have noticed an error with the kernel upgrade.  I haven't rebooted yet, I don't think it will boot.

Comment 1 Silviu Marin-Caea 2008-10-02 13:34:02 UTC 
Also, it seems it uses an awful lot of modules for a desktop Dell PC.
Comment 2 Robert Vojcik 2008-10-02 14:02:20 UTC 
Hello,

could you provide /var/log/zypper.log ?

Thanks
Comment 3 Silviu Marin-Caea 2008-10-02 14:06:49 UTC 
It booted, and now mkinitrd seems to run without the reiserfs error.

However there are still way too many modules.

Comment 5 Silviu Marin-Caea 2008-10-02 14:17:40 UTC 
I have unpacked the initrd and it has indeed a lot of useless modules for booting.  Like idetape.ko.  I think it has all the modules.  It doesn't seem normal, but maybe it's a new behavior, to include all modules.
Comment 6 Hans-Peter Holler 2008-10-02 14:32:44 UTC 
From the changelog:

* Di Sep 09 2008 hare@suse.de
- Fix dhcp network detection (bnc#415438)
- parse 'ip route' lines correctly (bnc#414191)
- Always include all ATA and SCSI drivers
Comment 7 Silviu Marin-Caea 2008-10-03 07:40:40 UTC 
Since this is expected new behaviour, I'll close the bug as invalid.
Comment 8 Felix Miata 2008-10-03 08:26:46 UTC 
Expected by who and why?
Comment 9 Silviu Marin-Caea 2008-10-03 09:21:42 UTC 
By hare@suse.de.  Why?  I presume because it's simpler, because systems have a lot of memory and because the initrd is cleared from memory anyway after the local storage becomes visible.  So it doesn't make sense maintaining code that detects the actual hardware and inserts only those modules in initrd.

But this is just my own assumption, hare@suse.de can provide the actual explanation.
Comment 10 Andreas Jaeger 2008-10-03 11:22:53 UTC 
Let's ask Hannes for his reasoning since it's not given in the changelog and there's no reference.
Comment 11 Hannes Reinecke 2008-10-09 11:12:33 UTC 
That was an error; we should only be include all libata drivers, and even those only if a libata driver was used for the root device (cf bug#433105).
Will be fixed with Beta3.
