Hi all!
Ok, another proposal, after I have read through the whole bug report:
A map file is either enabled or not, and either in automatic mode or
not, ie. auto=managed by the system, manual= managed by root
enabled/disabled is shown by #! starting in updmap.cfg
at the end of the map line we save the system state and the current
mode, eg with
# sys mode
eg
# 1 auto
# 0 auto
# 1 manual
# 0 manual
meaning that
1 enabled in auto mode
0 disabled in auto mode
auto this line is automatically managed
manual this line is manually managed
we have the following 5 actions:
enable
disable
system-enable
system-disable
auto (switches back to auto mode)
So we have the states
{auto,manual}/{enabled,disabled}
and have to define transitions for these states for the 5 actions:
A=auto
M=manual
E=enabled
D=disabled
Transitions:
action enable -E->:
-------------------
all states -E-> M/E
action disable -D->:
--------------------
all states -D-> M/D
action system-enable -SE->:
---------------------------
this action also changes 0 -> 1
A/E -SE-> A/E
A/D -SE-> A/E
M/E -SE-> M/E
M/D -SE-> M/D
action system-disable -SD->:
----------------------------
this action also changes 1 -> 0
A/E -SD-> A/D
A/D -SD-> A/D
M/E -SD-> M/E
M/D -SD-> M/D
action auto -A->:
-----------------
A/E -A-> A/E
A/D -A-> A/D
M/E -A-> A/use info from 0/1
M/D -A-> A/use info from 0/1
As long as we leave the file in /var/lib/ somewhere and the user does
NOT edit the file by hand, messing up everything, this should be enough
to solve the problems.
Best wishes
Norbert

You're bound to be unhappy if you optimize everything.
