Running scratchbox as root

So, I'll say at the beginning: I understand why developing
as root in
SB is A Bad Thing 

That said, I would like to be able to do so in very specific
circumstances, like when building up a fresh target (to
become the
image for a target device) by downloading/installing
packages with
APT.

Since package post-installation scripts sometimes need to
make device
nodes, or tweak binaries to be set-uid root, this seems to
be a
legitimate function.

Is there a way that I can override the safety checks and do
some work
as root? E.g.,

# /scratchbox/login apt-get install packages-for-target

Hi,

Fakeroot:

/scratchbox/login fakeroot apt-get install
packages-for-target

Fakeroot does not allow chown or mknod commands to achieve
their
intended result. The host system's kernel still pays
attention to
permissions. Transcript follows:

/scratchbox/login fakeroot mknod /tmp/blah c 1 2
/scratchbox/login ls -al /tmp/blah

    -rw-r--r-- 1 yourname yourgroup 0 Jun 20 16:43 /tmp/blah

mknod running underneath fakeroot just creates a normal
file.

I've added sudo for scratchbox (/scratchbox/tools/bin) and
it works fine 
for me

Within the fakeroot session that file looks like what you'd
expect.  
You must create the tarball/whatever within the same
invocation of  
fakeroot.

You can save fakeroot's database and load it when you want
to archive
the files:

	fakeroot -s database mknod /tmp/blah c 1 2
	fakeroot -i database tar cf ...

You can combine -i and -s if you work on the same database
on multiple
instances.  You can also save separate database files from
separate
operations (such as installing a particular package) and
concatenate
them before archiving everything.
