So I thought I'd have a bit of a fiddle with LVM2's snapshot feature, given
there's been a bit of discussion about it lately.
Turns out, if pbuilder were to use this, it'd greatly speed up the chroot
What I did was create a logical volume for use as the chroot "master" if you
will, and unpacked a tarball of a pbuilder chroot into it.
I then created a snapshot logical volume that used this "master" logical
volume. Pretty much instant copy. Mounted the snapshot volume, and ran amok
on it. Then unmounted it, removed it, and the original "master" logical
volume is still in its original state. Sounds good to me. I wonder if the
Debian buildds would benefit from this as well?
