A problem with variables in 1.4

Hash: SHA1

It appears that a problem was introduced in the 1.4 release on my fedora
10 laptop.  The following section of the %post section of my kickstarts
used to poduce a desired host name of dbg01.dbg.gesi (or whatever node I
was building).

# set hostname and populate hosts file
cat >> /etc/sysconfig/networking << EOF
NETWORKING=yes
HOSTNAME=$grid$node.dbg.gesi
EOF

%hostname produces: dbg.dbg.gesi.

If I escape the . after the variable as follows:

# set hostname and populate hosts file
cat >> /etc/sysconfig/networking << EOF
NETWORKING=yes
HOSTNAME=$grid$node\.dbg.gesi
EOF

%hostname is dbg01.dbg.gesi.  The /etc/sysconfig/network file keeps the
\, as expected.

Try something like this:

# set hostname and populate hosts file
#raw
cat >> /etc/sysconfig/networking << EOF
NETWORKING=yes
HOSTNAME=$grid$node.dbg.gesi
EOF
#end raw

I don't think Cheetah won't evaluate the $grid in your example either 
(raw means don't evaluate anything), but you could do something clever like:

#set $myhost="$grid"+"$node"+".dg.gesi"

and then in the next line

HOSTNAME=$myhost

I'm not sure why it would be a regression in what you had, but that 
should be plenty safe...
