I will allow myself to respond to my own posting.  It looks
like that I found a suitable hack.  With /etc/beowulf/node_up
as follows:

#!/bin/sh
/usr/lib/beoboot/bin/node_up $* || exit 1
echo "bpsh $1 /usr/sbin/gmond" | at now 2> /dev/null

this does what I wanted.  Clearly this may be used to run much
more extensive sets of commands.  The trick seems to be that
'at' executes everything in a different context than a direct
startup for a node.  Still if somebody have better ideas I am
all ears.

Interestingly enogh 'ps uwwaxf' has the following to show on a master
node:

root      3897  0.0  0.0     0    0 ?        RWN  23:15   0:00 [gmond]
root      3898  0.0  0.0     0    0 ?        RWN  23:15   0:00  \_ [gmond]
root      3899  0.0  0.0     0    0 ?        RWN  23:15   0:00      \_ [gmond]
root      3900  0.0  0.0     0    0 ?        RWN  23:15   0:00      \_ [gmond]
root      3901  0.0  0.0     0    0 ?        RWN  23:15   0:00      \_ [gmond]
root      3902  0.0  0.0     0    0 ?        RWN  23:15   0:00      \_ [gmond]
root      3903  0.0  0.0     0    0 ?        SWN  23:15   0:00      \_ [gmond]
root      3904  0.0  0.0     0    0 ?        SWN  23:15   0:00      \_ [gmond]

although 'bpsh 0 ps uwwaxf' comes only with this:

root      3897  0.0  0.1 15816 1384 ?        SN   23:15   0:00 /usr/sbin/gmond
