Not wanting to beat a dead horse... but isn't the usual method of
dealing with this simply a command line parameter which would specify
the location of the config file which would then specify the TopDir
whose value is not used to access the config file ?
ie, either the program uses it's hardcoded default value (or tries 3 or
4 values in a specific order that the package builder can customise if
needed)
OR
the user will specify the full path of the config.pl file as a command
line parameter at run-time...
Sure, there are a lot of 'standalone' applications in backuppc, but if
the user wants to use a non-default config.pl location, then they will
know they need to specify it when calling those applications...
Just my 2c
