Description of Problem:
The netfs init script has some errors that could stop it from functioning 
properly. More specifically:

line 28:
NETDEVMTAB=`grep -v '^#' /proc/mounts | awk '{ if (($4 ~ /_netdev$/) && 
($2 != "/")) print $2}'`
I am not sure if this is a problem but the patterm '/_netdev$/' in the 
awk program assumes that _netdev will only be found if it is at the end 
of the 4th field (mount options) in /proc/mounts. In another similar awk 
program later in the script (line 82) there is once again the 
pattern '/_netdev/'. In that case, it doesn't have to be at the end of 
the field. I suggest that '$' is removed from the pattern (see the 
proposed patch below).

line 74:
while [ -n "$remaining" -a "$retry" -gt 0 ]
This loop occurs in the context of: '[ -n "$NETDEVMTAB" ] && { ... }' 
(line 71-89). In this case there is an error that may prevent network 
block filesystems (mounted with the _netdev option) to be properly 
unmounted. The problem is that the variable $remaining is not set before 
the loop starts, unlike with loop devices (line 48) and NFS filesystems 
(line 93) where it is set before a similar 'while' loop begins. As a 
result, if this variable is not set previously, the loop will never be 
executed because $remaining is null and the '-n "$remaining"' condition 
is not met. I suggest the variable should be assigned before the 
execution of this loop. See the proposed patch.
