I copied a root partition using the "tar pipe" examples:
tar cf - ./bin ./boot ./dev ./etc ./home ./lib ./misc ./mnt ./root ./sbin ./tmp ./usr ./var | (cd /raidtemp;tar xf -)
in section 4.3 "Advanced configuration" of "The Red Hat Linux 6.1 SOFTWARE RAID HOWTO."
When I booted the partition I saw multiple daemon failures apparently caused by file protection problems.
When I changed the tar "restore" from "tar xf -" to "tar xpf -" the results were much more pleasing.
I recommend that the "tar pipe" examples in the aforementioned document be corrected.
This is a documentation issue.
This is really an issue for the Software-RAID tips maintainer to look into - I
am just going to mail firstname.lastname@example.org to make them aware of this minor nit,
and close this very old bug.
Sorry for the very long delay in replying.
