- Getting *everything* in a tar-file
- Posted by Baard Ove Kopperud on March 6th, 2004
I *know* this is a newbie-question, but I ask
just to make sure I don't do this wrong...
I've badly miscalculated the size needed for
a distro I've installed, so now that partition
is *nearly* full. I need to repartisonate my
disk.
Instead of installing everything again, I was
toying with the idea of just putting everything
into a (compressed) tar-archive on another disk...
Problem is, although I use tar often, I'm not
*quite* sure which options need to be given
to get everything -- including device-special
files, sockets and symbolic-links...
I'm most unsure about symbolic-links (device-
and socket-files should be OK, right), I
want them to stay symbolic, and neither be
replaced by the files they points to nor removed.

You still have to go through the partitioning and boot load installation
process. I would recommend it is easier to just reinstall the whole
thing.
Why not just create a small directory, put some sockets (mksock),
some pipes (mkfifo), devices (mknod), and soft/hard links. Then
you can play with it.
BTW symlinks are backed up symlinks, but AFAIK sockets are ignored.
Also, if you are tight on the other disk, then use bzip (j switch
for tar) since that compresses better (and slower) than gzip.

Baard Ove Kopperud enlightened us with:
If you *know* that, why don't you use Google to find your answer within
seconds?
Check out parted, it allows you to resize partitions non-destructively.

The problem with the world is stupidity. Not saying there should be a
capital punishment for stupidity, but why don't we just take the
safety labels off of everything and let the problem solve itself?

You don't want to include sockets. Those get created by running
programs and are meaningless once that program has terminated. Tar will
always skip sockets. Tar will include everything else by default. The
only option you might consider is "-S" (--sparse), which will prevent
any sparse files from being padded with zeros in the archive.
When you restore the files (as root), be sure to include the "-p" option
so that the current umask will be ignored when setting permissions on
the restored files.
