• In the wusr.conf file add or update as follows:
AUTOMOUNT_PREFIXES=<configured AUTOMOUNT PATH>:/nfs.
For example, to cause /nfs to be replaced by /net, add or update the
AUTOMOUNT_PREFIXES definition to:AUTOMOUNT_PREFIXES=/net:/nfs
HP DDE Behavior of the Step and Signal Handler
If a signal is delivered to a target process when DDE attempts to single-
step or step-over the process, and if DDE does not intercept the signal,
then DDE 4.23 prints a message and continues normal step execution.
NOTE The "next" statement may be the same statement that you just tried to
step past. It may also be the start of the signal handler if the signal
handler is compiled with -g. DDE does not distinguish between a
statement that loops back on itself or a statement that was interrupted
by a signal.
The jump into the signal handling code is treated as a normal call
situation. Since the signal handler will return to the first instruction to
execute—instead of the following instruction—it may be confusing that a
step produced no obvious action.
A step stops when it reaches the first instruction of a debuggable
statement. When a signal occurs during the step, that instruction is
typically the first in statement the user just attempted to step past. To
reduce confusion, when the step routine detects that an interrupt
(signal) has occurred while a step was being tried, an informational
message is printed in the DDE transcript. This message will indicate
that a signal was delivered to the target when the step attempt was
made.
