Upstream hashes both the absolute file name and the content of a file
|
||
to derive the name for the natively compiled files. This breaks the
|
||
staged install used in guix, as any $GUIX_PROFILE is distinct from
|
||
the build directory. It also breaks grafts, as hardcoded store file
|
||
names get rewritten; thus changing the file hash.
|
||
|
||
In addition, this patch changes how native-comp-eln-load-path is
|
||
constructed. Upstream, an entry of the directory “../lisp” is added
|
||
supposedly for bootstrap only, but this directory appears to find its
|
||
way into the actual variable despite attempts to remove it by calling
|
||
‘startup--update-eln-cache’.
|
||
The user-visible procedure ‘startup-redirect-eln-cache’ is kept, as
|
||
packages may require it, but only pushes the new value now.
