jilles 6ef9696fb4 sed: Try hard links to make -i target available continually. ... When creating a backup file, sed renamed the original before renaming the changed copy into place, leading to a short time when no file with the original name was present (usually only visible on SMP systems). Try creating the backup file using a hard link instead, avoiding this problem. If creating the hard link fails for any reason, fall back to the old rename method. When not creating a backup file, sed already renamed the changed copy onto the original. This remains unchanged. I am not adding the suppression of redundant fchown/fchmod to this commit, because FreeBSD appears to check this in the kernel (for msdosfs at least). PR: bin/153261 Submitted by: Pedro F.
