tar cannot read the entire /proc tree, but that is mostly the pid's

I normally exclude /proc from the tar since its contents are virtual.
/dev is ok to tar, GNU tar knows what to do with device files.

With /proc, just creating the directory should be sufficient since it's
dynamically created and altered as Linux runs. /dev can change,
however unless udev is being used, the individual devices can be copied
and used quite easily.

Thanks for all information and help
this weekends would be relaxed right at the box to move data to the new one.
cheers

/proc is a seperate filesystem. if you give tar the --one-file-system,
it will be excluded. tarring it up is kind of pointless anyway, since
only a snapshot of it's outputs is preserved, and restoring it does not
producce a functional proc filesystem.

note, just for giggles, that you can mount a proc filesystem anywhere.
eg., mkdir /tmp/foo && mount -t proc none /tmp/foo.

but above /dev, i just did a fast test, tar -cpf /tmp/dev.tgz /dev/,
and tar did bitch about socket /dev/log ... not sure if that's a
problem or not. but i've never notied any negative results from
using the technique in practice.

but of course - what is the point of newer, bigger, and
faster if not to fill it up, tear it up, and wear it out ?

Yes, that's the other little detail, tar doesn't grab Unix sockets but
that's ok since those will be created by the app that needs them on the
other side.

I think its advisable to replace (cd ${NEWMNT} ; tar -xpf - ) with
(cd ${NEWMNT} && tar -xpf - ) so that in the case of making some typo
in ${NEWMNT} you don't end up messing your files...

yes, you're right, very good point.

Maybe I do stuff wrong but I just go into the root directory of the old
drive and do this, which works everytime BTW. In fact just did it last
week.

cd /
cp -a * /newdrive



Make sure and do all the necessary fstab stuff and yer done.
pretty simple, but then I'm a simple minded kinda guy.

PS, yeah I know about dot files but I have never had any
in my / directory and the dot files in all the other directories
copy just fine.
