- Subject: [PATCH] scripts/Makefile.headersinst: install headers from scratch file
- If headers_install is executed from a deep/long directory structure, the
- shell's maximum argument length can be execeeded, which breaks the operation
- with:
- | make[2]: execvp: /bin/sh: Argument list too long
- | make[2]: ***
- By dumping the input files to a scratch file and using xargs to read the
- input list from the scratch file, we can avoid blowing out the maximum
- argument size and install headers in a long path name environment.
