atmos

Merge install prefixes though removable symlinks.

Getting started

Installations should be done into separate directories in a root directory. In the example below, we install some_library to ~/atmos/some_library and make symlinks to it in /usr/local/.

atmos set atmos_root ~/atmos
atmos set dest_root /usr/local

mkdir some_library/build
cd some_library/build
cmake .. install --prefix ~/atmos/some_library
make && make install

sudo atmos link some_library

To undo the symlinks, you can run the following

sudo atmos unlink some_library

Symlinks in libraries

Files are linked to the destination as absolute symlinks. Symlinks are transported as-is, so relative targets resolve in the destination:

~/atmos/mylib/lib/libfoo.so -> libfoo.so.1
/usr/local/lib/libfoo.so    -> libfoo.so.1

Unlink libraries before deleting them from the atmos root, or unlink --full will not be able to attribute their transported links.
