# Alternatives
+
+ 
Alternatives are install in /usr/local/share/alternatives
+ 
For a given alternative X we have a subdirectory alternatives/X
+ 
Then a files with the various alternatives names for each alternative
+ 
alternatives/php/7.2
+ 
alternatives/php/7.4
+
+ 
A special alternatives is provided by the repo based on DEFAULT\_VERSION when
+ 
the alternative is version based, or a specific KNOBS when not based on version
+ 
this add a new file (symlink) to the package alternatives/php/default -> 7.2
+
+ 
The alternative file is a ucl file, with a list of symlinks:
+
+ 
Description: "yeah baby"
+ 
symlinks {
+ 
	file1: target1
+ 
	file2: target2
+ 
	file3: target3
+ 
}
+ 
exec: { type = lua; script: ... },
+ 
exec: { type = shell; script: ...}
+
+ 
The exec part is an optional script which could be use to regenerate caches if needed for example
+
+ 
In case pkg 2 pkg have the default symlink then the regular conflict mechanism would be used
+ 
By default pkg priorize user defined default before package defined repo
+ 
if user defined repo to not exists then it switches to the global defaut if in non interactive
+ 
or as the user if in interractives mode
