ia32-libs vs. ia32 chroot

["Philip Warrick" <Philip.warrick@mcgill.ca>]

(Sorry for the no-subject post)

My /etc/apt/sources.list in the chroot looks like this:

deb ftp://ftp.debian.org/debian/ testing main
deb-src ftp://ftp.debian.org/debian/ testing main
# deb http://security.debian.org/ testing/updates main

as created by apt-setup (I said no the the security option, not knowing if I wanted this).

These files do exist in the chroot: /etc/hosts, /etc/passwd, /etc/group (not /etc/groups), /etc/shadow,
/proc (as described in the AMD-64 How-to).  I had done nothing with /etc/mtab and its entries were:

proc /proc proc rw 0 0

whereas my chroot /etc/mtab was simply

/dev/sda7 / ext3 rw,errors=remount-ro 0 0
proc /proc proc rw 0 0
devpts /dev/pts devpts rw,gid=5,mode=620 0 0
proc /var/chroot/sid-ia32/proc proc rw 0 0
/dev/sda1 /mnt/winC ntfs ro,noexec,nosuid,nodev,umask=0222 0 0
/dev/sda5 /mnt/winD ntfs ro,noexec,nosuid,nodev,umask=0222 0 0
/home /var/chroot/sid-ia32/home none rw,bind 0 0
/tmp /var/chroot/sid-ia32/tmp none rw,bind 0 0
//lmsrd01/DataDrive /mnt/lmsrd01 smbfs rw 0 0
/dev/sda6 /mnt/winE vfat rw,noexec,nosuid,gid=100,umask=000 0 0

Following ?good? advice elsewhere (http://hacktavista.com/howto/chroot_slackware.html) I did the following for the mtab file:
rm -f /etc/mtab
ln -s /proc/mounts /etc/mtab

the contents of /proc/mounts in the chroot are:

rootfs / rootfs rw 0 0
/dev2/root2 / ext3 rw 0 0
proc /proc proc rw,nodiratime 0 0
devpts /dev/pts devpts rw 0 0
proc /var/chroot/sid-ia32/proc proc rw,nodiratime 0 0
/dev/sda1 /mnt/winC ntfs ro,noatime,nodiratime,nosuid,nodev,noexec,uid=0,gid=0,umask=0222,nls=cp437,errors=continue,mft_zone_multiplier=1 0 0
/dev/sda5 /mnt/winD ntfs ro,noatime,nodiratime,nosuid,nodev,noexec,uid=0,gid=0,umask=0222,nls=cp437,errors=continue,mft_zone_multiplier=1 0 0
/dev2/root2 /var/chroot/sid-ia32/home ext3 rw 0 0
/dev2/root2 /var/chroot/sid-ia32/tmp ext3 rw 0 0
//lmsrd01/DataDrive /mnt/lmsrd01 smbfs rw,nodiratime,nosuid,nodev,file_mode=0744,dir_mode=0755 0 0
/dev/sda6 /mnt/winE vfat rw,nodiratime,nosuid,noexec,gid=100,fmask=0000,dmask=0000 0 0

After all that I still get the same errors.  apt is definitely able to connect (apt-get update downloaded some packages successfully).

Any ideas?

Thanks,

Phil

Don't forget /etc/hosts, /etc/passwd, /etc/groups, /etc/shadow,
/etc/mtab, /proc in the chroot.
