Hi,
I have three questions. First, when I chroot to
/var/lib/diskless/default/root and install new packages, /etc and /var
updates don't propagate to the host /etc and /var directories. Are
there plans to make this work -- for example, to have a
"diskless-update" script to update all of those dirs?
I think that would be very difficult to implement, considering that
the differences on each individual clients would be
pretty difficult to track, to say the least.
Hmm... How about ending diskless-newimage with something like:
touch $diskless-rootdir/lastupdate
(I don't know what the real diskless-rootdir variable should be, nor
diskless-hostdirs below.) Then diskless-update could have something like:
for newconffile in \
`find $diskless-root/etc -newer $diskless-rootdir/lastupdate -print`; \
do \
for hostdir in $diskless-hostdirs; do \
cp -i $newconffile `echo $newconffile | sed s/$diskless-root/$hostdir/`;
done; \
done
Unfortunately, this wouldn't work for /var because it would copy things
like /var/run and /var/spool, which is bad.
Or one could look in $diskless-rootdir/var/lib/dpkg/info for new
.conffile files and use those to update the directories... Is there
some kind of hook mechanism for installing conffiles in dpkg?
Second, woody seems to have a new way of installing base using packages
in basedebs.tar instead of base.tgz. Are there plans to update diskless
accordingly, e.g. using dpkg --install --root?
diskless-createbasetgz exists for creating base.tgz.
It should be possible to run debootstrap on each run to
diskless-newhost.
I see, that's cool. (Do you mean diskless-newimage instead of
diskless-newhost?)
However, requiring diskless-createbasetgz to be called once,
and using the resultant base.tgz is faster than requiring
debootstrap to be ran on each time.
That makes sense.
Third, is there a way to make the console work so users can log in
there? I always get something like "id 1 respawning too fast, disabling
for 5 minutes".
Init is in /sbin/init, AFAIK, and it is a shell script installed by
diskless-image-{simple,secure} package.
You may want to read it to see what might be causing it...
and yes, it should probably be respawning too fast by the look of it.
I see. I guess it wasn't meant for console use. :-) Maybe the console
entries in inittab should be commented?
One could probably switch to runlevel 5 and run a *dm just fine for a
workstation cluster...
Well, this isn't my intended application, so I'll let somebody else
experiment with that.
I haven't had much time to work with this package recently, and help would be
appreciated.
Okay, we'll see what we can come up with.
Thanks again for a really nice package!
