hi,
i'm really sorry to be bothering people on this list but i genuinely
don't what phrases to google for what i am looking for without getting
swamped by useless pages, which you will understand why when you see
the question, below.
the question is, therefore:
* how the hell do you loopback mount (or lvm mount
or _anything_! something!) partitions that have
been created in a loopback'd file!!!!
[aside from booting up a second pre-installed xen
guest domain and making the filesystem-in-a-file
available as /dev/hdb of course.]
answers of the form "work out where the partitions are, then use
hexedit to remove the first few blocks" will win no prizes here.
The bad news: it was impossible (or at least very hard to do).
The good news: it is possible now. The anwser is:
- figure where the partitions are (possibly using some simple script),
- use device-mapper to create block devices covering partitions,
- mount them.
I do not know if this anwser will win your price but it is IMHO far better
than hexedit... :-) And probably this is the only anwser.
(IIRC if you have one partition you can skip partition table with offset
option to losetup. But this will only work in this special case...)
