[pacman-dev] dangerous symlink handling with --root option

Hi again,

(and sorry again for any split lines)

Okay, so I was fooling around with the --root option
again, and after I realized from one of Xavier's posts
that pre/post install scriptlets won't be run at all
until /bin/sh (from bash) is installed, I figured I
should install the packages twice. This led to two
issues. I have a bash script (attached) that basically

pkglist=( ... bunch o' base packages ... )
mkdir /tmp/pacman.test
pacman -U --root /tmp/pacman.test ${pkglist[*]}
pacman -U --root /tmp/pacman.test ${pkglist[*]}

The second install of coreutils causes:

error: cannot remove file
'/tmp/pacman.test/usr/bin/sleep': Read-only file
error: failed to commit transaction (transaction
error: failed to release transaction (could not commit

First Issue: CPU usage then goes to 100%, so I assume
that pacman has gone into an infinite loop somewhere. 

Second Issue: the real concern is the "Read-only file
system" error, since /tmp is on a tmpfs and is
definitely not read-only. My / partition is read-only
though, and

# ls -l /tmp/pacman.test/usr/bin/sleep

lrwxrwxrwx 1 root root 10 2007-08-16 16:13
/tmp/pacman.test/usr/bin/sleep -> /bin/sleep

So pacman was following the absolute symlink *out* of
the --root and trying to remove /bin/sleep from my
main arch install ??
