Re: svscanboot and environment variables

 svscanboot is a shell script, so you can edit it and remove the
"env - PATH=$PATH" part before "svscan". This will keep the environment,
apart from the PATH that is set at the top of the script.

 Alternatively, you can install execline
<URL: http://www.skarnet.org/software/execline/ > and use the script
provided in attachment, removing the /command/emptyenv and maybe
/command/export lines at the top of the script. This is an exact rewrite
of the svscanboot script; the benefit is that you don't keep a /bin/sh
running along with svscan and readproctitle.

 Better yet is to forget readproctitle and use a catch-all logging
service by having svscan writing to a fifo and some (supervised) multilog
reading from that fifo. The setup has been discussed on the supervision
list ([email protected]).

 I don't know AIX, but I'd advise to stick to DJB's way - calling a script
from /etc/inittab - modifying the script if necessary. You never know:
you might be bitten by some hidden inittab non-portability, or by the
fearful process group trap.
 (Or you might forget init and run svscan as process 1, as Paul and I do,
but I suppose that's not an option.)
