From 0272fca993718460bf7ecb7fdc3ca7dad1c7e6cd Mon Sep 17 00:00:00 2001 From: Eli Schwartz Date: Sun, 27 Oct 2019 03:41:46 -0400 Subject: makepkg: do not count hard links multiple times when calculating pkg size Exclude files with hardlinks when cat'ing all the files, and do a second run to look at each file with hardlinks, keep track of the ones we've already operated on, and only cat each inode once. Then use "wc -c" to get the size of all (deduplicated) files the same way we were already doing.
