[SOLVED]minimal cd install

[warren13n]

Hi, I just discovered Gentoo and am trying to install from the handbook ( x86_64 minimal cd ). I have made it to step 7d and did emerge genkernel. My problem is that I am travelling and staying in hotels. I only has this laptop, so to check my e-mails I have to shut down and boot the (very cool ) 11.2 live dvd. My first of many questions is can I continue my build from the live dvd? This would be very convenient! When I go into Terminal I can't su. Do I need to mount the partitions again? Thanks for your help. I may be delayed in responding.

to pick back up where you left off on an install, assuming you've already untarred the stage and portage tarballs (which you have), all you need to do is

-boot whichever livecd/livedvd/liveusb you like
-mount your root partition
-mount any other partitions
-turn on swap
-mount proc and dev
-chroot
-pick back up where you left off (in this case with the kernel configuration stage)

you can use gentoo's livedvd, or any other livecd that allows you to mount partitions and chroot. i always carry sysrescuecd on a thumb drive with me, as a swiss army knife, but it's also how i do my gentoo installs (no deviation from the handbook's steps).

The only thing to make sure of - if you used a 64bit (amd64) stage3 tarball, you will want to boot a 64bit kernel from whatever media you use
if you used a 32bit (x86) stage3 tarball, you will want to boot a 32bit kernel

regarding the inability to su - try "sudo su -" and see if that works.

sudo su worked. Thank you cach0rr0.
