Even xeyes! Thanks for the idea of (duhh...) doing uname -a. I'll use
that below. This is almost certainly that I'm still doing something
wrong. The 32-bit environment is still there, and does work for root
as it always has, but l32 (assuming that l32 /bin/bash is the right
command) isn't working for me as a user. I'll start in my 64-bit
world:

mark@lightning ~ $ uname -a
Linux lightning 2.6.14-rt22 #1 PREEMPT Mon Dec 5 10:17:06 PST 2005
x86_64 AMD Athlon(tm) 64 Processor 3000+ AuthenticAMD GNU/Linux
mark@lightning ~ $ l32 /bin/bash
mark@lightning / $ uname -a
Linux lightning 2.6.14-rt22 #1 PREEMPT Mon Dec 5 10:17:06 PST 2005
x86_64 AMD Athlon(tm) 64 Processor 3000+ AuthenticAMD GNU/Linux
mark@lightning / $ exit
exit
mark@lightning ~ $

So, even though l32 ran I mistakenly thought I was in the 32-bit
environment. I'm not, and neither is root. Again, starting from
64-bit:

mark@lightning ~ $ su -
Password:
lightning ~ # l32 /bin/bash
lightning ~ # uname -a
Linux lightning 2.6.14-rt22 #1 PREEMPT Mon Dec 5 10:17:06 PST 2005
x86_64 AMD Athlon(tm) 64 Processor 3000+ AuthenticAMD GNU/Linux
lightning ~ # exit
exit
lightning ~ #

However the big command does work, but for root only:

lightning ~ # linux32 chroot /mnt/gentoo32 /bin/bash
lightning / # uname -a
Linux lightning 2.6.14-rt22 #1 PREEMPT Mon Dec 5 10:17:06 PST 2005
i686 AMD Athlon(tm) 64 Processor 3000+ AuthenticAMD GNU/Linux
lightning / #

Show me the error of my ways!

Thanks,
Mark
