Archlinux32, i486 ISO for low-memory systems

Enable a network first with for instance 'dhclient'.

Create and mount a swap partition and mount a /tmp to 
/mnt/tmp as bind mountpoint as very first action before
trying to install something with pacstrap/pacman..

The CD is read-only, you may want to copy '/etc/pacman.conf'
to '/tmp/pacman.conf' and use 'pacstrap -c /tmp/pacman.conf'
if you have to change settings.

With less than 196MB RAM pacman/gpg fails to verify
signatures, create a local /mnt/pacman.conf where you
set 'SigLevel=Never' and specify '-C /mnt/pacman.conf'.

With less than 96MB RAM mkinitio on tmpfs fails with
out of disk space, use 'TMPDIR=/var/tmp mkinitcpio -P'
inside the chroot to create it. With 64MB RAM use
'gzip' and not 'xz' or 'zstd' as COMPRESSION method.

Consider disabling tmpfs for /tmp on the installed
system too 'systemctl mask tmp.mount'.

Remember to compile your own static kernel or create
a stripped-down ramdisk if you have little memory.

Set 'iommu=off' to regain some memory.
