Description of problem:
sudo rpm -Fvh XFree86-xfs-4.3.0-12.i386.rpm
useradd: user xfs exists
error: %pre(XFree86-xfs-4.3.0-12) scriptlet failed, exit status 9
error:   install: %pre scriptlet failed (2), skipping XFree86-xfs-4.3.0-12

Seems like preinstall contains the following which fails if the user already
exists returning an errorcode ...

/usr/sbin/useradd -c "X Font Server" -r -s $LOGINSHELL -u 43 -d /etc/X11/fs xfs



Version-Release number of selected component (if applicable):
XFree86-xfs-4.3.0-12.i386.rpm

How reproducible:
Always

Steps to Reproduce:
1. rpm -Fvh XFree86-xfs*
2.
3.
    

Actual Results:  Install process aborts

Expected Results:  Shouldn't abort even if user "xfs" exists already (which is
the case with most systems)

Additional info:

The following would probably prevent the error condition (from the top of my head):

/usr/sbin/useradd -c "X Font Server" -r -s $LOGINSHELL -u 43 -d /etc/X11/fs xfs
2> /dev/null || :
