Hello,
hmm, once again me. And again with a probably not so common problem.
I need to replicate files, exactly like they are!
I thought cpio was the deal, but no way, I tried several -H formats but=20
that hasn't changed anything. As soon as a file gets restored the flag=20
arch is reset, same with nodump.
Then I remember Tim Kienzles great work for bsdtar and all the ACL stuff,=20
but unfortunately a cvPPzf <> xvpPfz also looses the arch flag :(
My temporary solution is the following, but I don't liek it:
for n in `/usr/bin/cpio -idmuv --quiet < ${varmfs_bufferdev} 2>&1`
do /bin/chflags arch $n
done
Dump is no alternative since I have to archive just selected files, cpio's=
=20
behaviour is the one I like most for my needs.
Any suggestions?
Thanks,
=2DHarry
P.S.: Here's a little panic I had today on my embedded system (RELENG_6=20
from today!), no debug kernel, too less memory, but if anybody's=20
interested, here's the message:
