| But what if there is no overarching directory? In my case I
| want to backup three partitions, but I certainly don't want to
| backup /.
| A quick fix (which seems to work for my system) is to create
| a little directory of symbolic links to the partitions I want,
| and tell mkisofs to follow links. But what if the partitions
| themselves contained links that pointed all over the shop?
this is where `--graft-point' is very possibly yer
mkisofs -R -o image -graft-points -- path_in_ISO/=path_on_HDD
note the trailing `/' in the magic dir/=dir argument;
AFAICR, it matters (at least when using the trick
described below?)! the path_in_ISO/ should not start
with `/'; nominally, path_on_HDD does. and usefully,
you can have multiple such arguments.
mkisofs(1) creates any dirs in the ISO necessary to
make path_in_ISO/ valid. the _problem_ (for me) with
the above is the mode/owner/group of those dirs is both
rubbish and uniform (identical). that may or may not
be Ok for you, but since it vastly annoyed me ....
.... I found a simple hack to work-around the problem:
I also create a little directory (as mentioned above),
not of symlinks, but of the directories named as they
are to appear in the ISO (i.e., path_in_ISO/ names).
I set the mode/owner/group of each directory to what
I want, and then:
mkisofs -R -o ../image -graft-points -- . path_in_ISO/=path_on_HDD
that is, `.' (the_little_dir) is first in the list of
things to put into the ISO, followed by the magical
path_in_ISO/=path_on_HDD argument(s). end result is
`mkisofs' creates the needed dirs as per my precise
specifications, and then uses them as per the graft
magic without creating any dirs on its own.
