This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
Add a few strategic screen clears.
Do a lot less wasted screen I/O in restoring screen contents that don't need
restoring.
Use tar instead of cp to back up /etc in installUpdate.
Don't panic when upgrade shell exits.
in one place, leaking memory in another).
Add a facility to invoke subsystems directly by naming them on
sysinstall's command-line when running post-install. A replacement
for pkg_manage might, for example, be `/stand/sysinstall configPackages'
Fix bogon where upgrade shell was entered with tty modes spammed.
Fix bug with release name checking in ftp_strat. Turned a bunch of
bogus exit()s into proper calls to systemShutdown().
1. Fix the last display bugs (I hope) by use of dialog rebuilds at stategic
points.
2. Clean up the distributions menus so that everybody (that's reasonable)
has All and Clear options for setting/clearing things en-masse.
3. Various attempts at display optimization.
4. Change the wording of the `Don't use Write!' dialogs to make them more
explicitly define when and when not to use the option.
I still have a _very very annoying_ display bug which occurs when a menu
item causes a submenu to be displayed - the screen repaints for the original
menu (which is restored upon return from the submenu) are off by about 4
characters. I've tried restoring the screen, the cursor position, you name
it - same deal. Grrrr! This commit is my first step in trying to get someone
else to help me look into this one since I'm just tearing my hair out at this
point!
1. Use new dialog menu hacks (no strings, just arrays of dialogMenuItem structs)
so that I can create composite menus with radio/checkbox/... items in them,
removing some long-standing UI bogons in various menus. This work isn't
finished yet, but will be done in two phases. This is phase one.
2. Remove all the script installation stuff. I never got time to document it,
it was arcane and it just complicated much of the code. There are better
ways of doing this if I want to do auto-driven installations later.
3. Remove much dead code and otherwise attempt to remove as much historical
grot as possible so that this code is easier to hack on. This is also
a two-stage process, phase one of which is now complete.
don't bogusly restore the screen to the message that was the cause of the
abort. That resulted in lots of weird flickering dialog boxes that appeared
to be displayed out of sequence.
