Hi all,
   Sorry for the delay responding. I'm back as of yesterday from my
class and starting to use my Gentoo AMD64 machine with it's chrooted
environment more intensely. Things are progressing pretty nicely:

Billy - I would agree with a default of /mnt/gentoo32 for now, just to
match the manual.

1) Everything seems to work fine so far as root. I have Firefox, Java,
Flash and mplayer all working nicely. I can browse the web pages I
need to and play the wmv video training files and do the exercises
just fine.

2) As a user, and using Peter's outline of how to fix my l32 setup, I
am now able to get to the chrooted environment as a user. Thanks
Peter! Note that I set it up as Peter suggested with the tar file in
/usr/local/portage/distfiles. I take it from reading the rest of this
thread that this is not required?

3) Ar root in the  chrroted environment I am not able to emerge vim
successfully:

lightning ~ # emerge -pv vim

These are the packages that I would merge, in order:

Calculating dependencies ...done!
[ebuild  N    ] app-editors/vim-6.4  -acl -bash-completion -cscope
+gpm -minimal +nls +perl +python -ruby -vim-with-x 0 kB

lightning ~ #

will fail like this:

I'm not clear what USE flags this message says should be the same.
Possibly I should remove the perl flag from vim???

lightning ~ # emerge -pv vim perl libperl

4) OK, after chrooting into the new environment (l32 /bin/bash) I can
run Firefox, but I'm surprised to see that I have all my bookmarks
from the 64-bit environment. Is this correct?

5) Probably most important, I do not have a user account in the
chrooted environment yet. I've found a couple of wiki's about doing
this but they seem contradictory so I'm taking that slowly. The lack
of the /home/mark directory seems to get in the way of pretty basic
stuff:

mark@lightning / $ java-config -L
[blackdown-jre-1.4.2.02] "Blackdown JRE 1.4.2.02"
(/etc/env.d/java/20blackdown-jre-1.4.2.02)
[blackdown-jdk-1.4.2.02] "Blackdown JDK 1.4.2.02"
(/etc/env.d/java/20blackdown-jdk-1.4.2.02) *
mark@lightning / $ java-config -s blackdown-jre-1.4.2.02
jc_options: Cannot write to ${HOME}
mark@lightning / $

If I create the directory by hand I suspect I'll create problems.

6) I am not sure I'm happy with the way the wiki set up my chrooted
environment. From the 64-bit environment I now see:
mark@lightning ~ $ df
Filesystem           1K-blocks      Used Available Use% Mounted on

It seems these mount -bind steps have hidden my normal disk partitions....


   Anyway, that's my quick status. Thanks in advance for all your help.

Cheers,
Mark
