Re: [gentoo-user] ... fails to open device '/dev/hda2' after update
Well, a local Gentoo-guru fixed the problem with etc-update. So the failure to appears to have been there. As, a newbie I could use some subtantial advice where, when, and how ect-update should be used (there were 80 config files to take care of) - although when I failed I wasn't even aware of the problem.

The message will say that there are x number of files in /etc that need updating. # etc-update Will return a list of files that need attention. selecting a file from the list shows differences between the new config file and the old one. generally, files that you haven't manually changed yourself can be safely updated to the newer version. Again, most of the time, for files that you have modified yourself, it is safe to retain your old file after checking to see if there are new features you might want. You will notice that there are several options for accepting the new files. One of them is -5 which will accept all of the new files without any further action on yout part. This is VERY dangerous! If you're not very sure what you're doing, don't use that option. -- Regards, Ernie -- gentoo-user@gentoo.org mailing list
RE: [gentoo-user] ... fails to open device '/dev/hda2' after update
I had the same thing happen on Friday on a VMWare I use for LAMP development. Just Control D to continue. Your drives should mount as normal. If you have a stock system, /dev/hda3 is where your goods are. Hda1 is just /boot and hda2 is swap, so don't worry about the error. Follow these instructions: http://www.gentoo.org/doc/en/udev-guide.xml Or http://gentoo-wiki.com/HOWTO_Migrate_to_UDEV Or http://webpages.charter.net/decibelshelp/LinuxHelp_UDEVPrimer.html It's pretty painless really. -Original Message- From: Fredrik Lundgren [mailto:[EMAIL PROTECTED] Sent: Saturday, January 28, 2006 5:41 AM To: gentoo-user@lists.gentoo.org Subject: [gentoo-user] ... fails to open device '/dev/hda2' after update Dear list, I haven't used my Gentoo for more than half a year or so (it was well updated then) so the other night I made an update emerge --update system and all appeared to go well (lots of updates) but when I rebooted i got * checking root filesystem ...

Kernels don't get compiled and installed automatically. I bet you still run your old kernel which was configured for devfs. Your update probably unmerged devfsd or whatever the daemon was called. Now, how to plumb the hole? Boot from a liveCD, Mount your partitions the way your fstab would do it, chroot into your system that's on the harddrive, compile the kernel with udev, update /boot/grub/grub.conf) run etc-update and finally reboot with a bottle of cheap (Lundgren's your name?) aquavit at hand. ;-) I have probably forgotten some steps but guess you get the picture. ;-) Uwe -- Unix is sexy: who | grep -i blonde | date cd ~; unzip; touch; strip; finger mount; gasp; yes; uptime; umount sleep -- gentoo-user@gentoo.org mailing list
