Got that network problem solved, now a new one

[Gene Heskett <gheskett@shentel.net>]

Greetings all;

I am, because my web page serves as a backup site for the os and some 
tools for use with the now 30 year old trs-80 color computers, have a 
script IP can run that pulls fresh copies of the sources for this code 
using hg, then builds fresh copies and makes it all available on my web 
page.

Unfortunately that script, running as me, suddenly has no write 
permissions to do what it does.  This has been working for several 
years.

This is the script:
============================
#!/bin/bash
# since I'm always forgetting who I am
if [ `whoami` != 'gene' ]; then
	echo
	echo "!!!!!!!!!!!!!!!!!! Warning !!!!!!!!!!!!!!!!!!!"
	echo "this script needs to be run by user gene"
	echo
	echo
	exit 1
fi
mv lwtools lwtools-$(date +%Y-%m-%d-%H-%M)
hg clone http://lwtools.projects.l-w.ca/hg/ lwtools
cd lwtools
make
sudo make install
cd ..
echo
echo
echo "lwtools has been built, next is toolshed"
echo
echo
chown -R gene:www-data lwtools # make visible to the web
mv toolshed toolshed-$(date +%Y-%m-%d-%H-%M)
hg clone http://hg.code.sf.net/p/toolshed/code toolshed
cd toolshed
make -C build/unix
sudo make install
cd hdbdos
make
cd ../..
chown -R gene:www-data toolshed
echo
echo
echo "toolshed has been built and installed, next is nitros9"
echo
echo
mv nitros9 nitros9-$(date +%Y-%m-%d-%H-%M)
hg clone http://hg.code.sf.net/p/nitros9/code nitros9
cd nitros9
export NITROS9DIR=$PWD
hgpull;hgupdate
mkdir dsks # this step is temporarily needed
make dsk
make dskcopy
cd ..
chown -R gene:www-data nitros9
echo
echo "nitros9 has been refreshed"
echo "this completes the build of lwtools, toolshed, and nitros9"
==================================
and its now being denied at the first mv operation. /opt of course is 
owned by root:root but that hasn't changed in 18 years of running linux.
This script has been running flawlessly about once a month since July 
2013 when I wrote it.

So what was changed to prevent the common user from using /opt as 
himself? cd'd to /opt, I can't even "touch ajunkfile".  Grrrrrr.  Me, 
goes in search of my LART.

Better yet, how can I fix it? /opt permissions are 40755, and I'm 
assuming a chmod 0777 as root would fix it temporarily, but thats one 
hell of a kludge.  I'd much rather find where the rules to this game are 
and get them fixed.

Thanks all.

Cheers, Gene Heskett
