EasyOS update fix for JWM

February 15, 2022 — BarryK

There was one report that updating EasyOS to 3.4 from 3.3 broke the desktop, whereas a new installation of 3.4 was OK.

I am trying to chase down what might go wrong when do an update. I have done it on two PCs without problems. One was an update from 3.1.11, the other from 3.3.

I discovered one potential problem, with JWM. The file /root/.jwmrc-tray has a different format in 3.4. File /root/.jwm/jwmrc-personal has changed with the upcoming 3.4.1. See a couple of earlier posts:

...the second link shows the new /root/.jwmrc-tray.

For Easy 3.4.1, /root/.jwm/jwmrc-personal will have some changes to enhance editability:

If someone does an update to 3.4 or 3.4.1, one or both of these files may be pre-existing and have an inappropriate format. So, in /sbin/fixlayers script in the initrd, now has this check:

#20220215 easy 3.4 has different format in /root/.jwmrc-tray
if [ -f /mnt/${WKG_DEV}/${WKG_DIR}.session/root/.jwmrc-tray ];then
 grep -q 'STARTMENU' /mnt/${WKG_DEV}/${WKG_DIR}.session/root/.jwmrc-tray
 if [ $? -ne 0 ];then
  rm -f /mnt/${WKG_DEV}/${WKG_DIR}.session/root/.jwmrc-tray
 fi
fi
#20220215 easy 3.4.1 has different format in /root/.jwm/jwmrc-personal
if [ -f /mnt/${WKG_DEV}/${WKG_DIR}.session/root/.jwm/jwmrc-personal ];then
 grep -q 'STARTWINDOWSTYLE' /mnt/${WKG_DEV}/${WKG_DIR}.session/root/.jwm/jwmrc-personal
 if [ $? -ne 0 ];then
  rm -f /mnt/${WKG_DEV}/${WKG_DIR}.session/root/.jwm/jwmrc-personal
 fi
fi

Changing the subject, two 3.4 testers reported that they would prefer bigger icons in the tray. I have increased the tray height from 26 to 32. Also, the icons in .jwmrc-tray are changed from *24.png to *48.png, so that they can scale down to fit the new height.
