While I was opening my Ubuntu system the electricity went off. When electricity was back I reopened the system and I faced with a crash of the system telling me unable to mount /proc etc.
I followed
http://art.ubuntuforums.org/showthread.php?t=1601810&highlight=mounting+dev+on+root+dev+failed+no+such+file+OR+directory&page=2
but it did not solve so I then reopen the system with a ubuntu livecd and made fsck -fC /dev/sdb1 command multiple times.
Yeah everything is back.
When I tried to install gentoo and finally open my system I realized that the ethernet connection was broken. After a search I saw that it was due to lack of the hdpc packet so I had to go back to the live CD and emerge it. If I want to emerge a packet on my system with a live CD then I should chroot. I simply adopted something from the installation guide of gentoo.
I opened the system with a live CD and fell into the gentoo live session then I did the following (I assume that you have configured eth0)
mkdir /mnt/temp
mount /dev/sda3 /mnt/temp
mirrorselect -i -o >> /mnt/temp/etc/make.conf
mirrorselect -i -r -o >> /mnt/temp/etc/make.conf
cp -L /etc/resolv.conf /mnt/temp/etc/
mount -t proc none /mnt/temp/proc
mount -o bind /dev /mnt/temp/dev
chroot /mnt/temp /bin/bash
env-update
>> Regenerating /etc/ld.so.cache...
source /etc/profile
export PS1="(chroot) $PS1" |
mkdir /mnt/temp
mount /dev/sda3 /mnt/temp
mirrorselect -i -o >> /mnt/temp/etc/make.conf
mirrorselect -i -r -o >> /mnt/temp/etc/make.conf
cp -L /etc/resolv.conf /mnt/temp/etc/
mount -t proc none /mnt/temp/proc
mount -o bind /dev /mnt/temp/dev
chroot /mnt/temp /bin/bash
env-update
>> Regenerating /etc/ld.so.cache...
source /etc/profile
export PS1="(chroot) $PS1"
now you have chroot and have an alive internet connection
emerge hdpc
>> when everything finishes
reboot |
emerge hdpc
>> when everything finishes
reboot
if you eject the live CD and permit the system start then you will have a system on which hdpc is installed.
