When I run this command:
composer install
I get the following output:
...snip...
- Installing acquia/blt (dev-DT-1201): Symlinking from /home/dane/packages/blt
And I expected this to happen:
The package in question to actually be linked as /home/dane/packages/blt. Instead, the package is linked using a relative path:
$ ls -al vendor/acquia/
drwxr-xr-x 2 dane dane 4096 Mar 18 18:27 .
drwxr-xr-x 60 dane dane 4096 Mar 18 18:27 ..
lrwxrwxrwx 1 dane dane 12 Mar 18 18:27 blt -> ../../../blt
It appears that Composer transforms the absolute path to a relative one if it shares any common parent directories. This is unexpected behavior IMHO, and creates problems that are difficult or impossible to work around. In my case, I'm using Composer to create a master test fixture that I want to clone elsewhere on my system as a testing sandbox, and that's impossible if the link is not absolute.
I'd like Composer to either maintain links as they are provided, or provide an argument/config to force them to be absolute.
