package: reintroduce/rewrite flat view (re: 20f8557c)
I called the flat view featuritis, but it turns out the dtksh build
system depends on it. But it was broken, so let's make a proper
version instead. This new approach does not symlink directories
before make, but hardlinks files after make. To make performance
tolerable, it requires a modern POSIX 'find' utility with '{} +'.
bin/package, src/cmd/INIT/package.sh:
- We're going to depend on 'test X -ef Y' to check if X is the same
file as Y, so add that to the $min_posix checks even though it is
not technically POSIX. But it's so close to universally available
it doesn't really make a difference.
- After 'make', create a flat view by hardlinking arch/$HOSTTYPE
files, minus build system internals, onto their corresponding
paths in $PACKAGEROOT. Fall back to symlinking if hardlinking
fails (this would happen when crossing device boundaries).
- Clean up flat view when doing clean/clobber. This is done by
using 'find' to loop through the files in arch/ again and
removing any root paths that are the same file as their
corresponding arch/ path (this is where test X -ef Y comes in).
Then delete arch/$HOSTTYPE, then delete empty directories left.
- Check for the 'flat' qualifier when doing clean/clobber. If
given, do not delete arch/$HOSTTYPE but only clean up the flat
view and remove empty directories.
src/cmd/INIT/Mamfile:
- Do not create the lib/package directory. (re: beb3c64a)
.gitignore:
- Update.
