How do copy my / containing directory root boot tmp bin
proc etc to a different partition of same disk.
I used dd if=/dev/sda1 of=/dev/sda4 but it seems to "hang".
cp -up could not handle /tmp correctly
Thank in advance for your reply.

AFAIK dd will only work if both partitions are the same size, which is
probably why it's hanging.
You don't need to copy proc, it should be created by the kernel - you may
need to manually make the /proc directory though.
As far as copying goes, a user on this list pointed out to me how to use
tar to do very good copies:
http://www.hantslug.org.uk/cgi-bin/wiki.pl?LinuxHints/OneDiskToAnother
namely, mount one partition as one thing (e.g. /mnt/first) and another as
something else (/mnt/second), then use a command similar to the following:
(cd /mnt/first && tar cfl - . ) | (cd /mnt/second && tar xvfp -)
Note that the "l" (that's an L) switch in the first half of the command
means that tar won't traverse to different partitions/filesystems, which
you may or may not want. I found that this copied all my device nodes over
nicely as well.
Don't forget to update your boot block!
