[gentoo-user] Accidentally deleted contents of /sbin

[gentoo-user] Accidentally deleted contents of /sbin

[James Colby]

List Members -

I was trying to delete some files from my /sbin directory and with an
unfortunate use of a wildcard accidentally deleted the entire contents
on the /sbin directory.  I have recovered the contents of the /sbin
directory from a stage 3 tarball.  I was thinking about doing an
emerge world, just to make sure that everything is consistent.  Do you
all think that this is necessary?

Thanks,
James

Oh, it's not really usefull to rebuild all
just rebuild this:

equery b /sbin

so. .. it will give you all package which install something in /sbin
just rebuild it

I suppose that remerging packages that install anything in /sbin would be in 
order:

# cd /var/db/pkg && emerge -va1 $(for pkg in */*; do
        cut -d' ' -f2 "${pkg}"/CONTENTS | grep -q '^/sbin/' && echo "=${pkg}"
    done)

Thanks for the advice everybody.  I ran this command and it just
finished successfully.  I had one file in /etc that needed updating,
and when I tried to run etc-update it was missing.  Should I try to
emerge world?

Thanks,
James

I'm not clear on what's happened.  Is it etc-update that's missing or is
it something else?

May want to emerge portage.  That is where that command comes from.

If it were me, I would still do a emerge -e world, just to be sure.

You can check all packages for missing or corrupt files with

equery -C list kdebase | awk '/\// {print $((NF - 1))}' | sed 's;^;=;' | xargs --max-lines=1 equery check

I have seen the truth, and it makes no sense.

Does emerge -e world add anything to the world file?  Do I need to add
the --oneshot option to this to keep my world file clean

>From what I understand, it takes the packages listed in the world file
and then pretends there is nothing emerged and builds a list.  This will
emerge everything in world plus their dependacies.  It should not change
your world file at all.  I have done this several times when something
goes weird on my system or upgrading gcc.  You have a good plan to keep
your world file clean though.  Seems we are both learning to do that.  O_O

Basically, this rebuilds everything on your system from the ground up. 
That is why it takes so long.  It's akin to rebuilding the whole house
when you have a small leak in your roof.  Of course, you have a new
house this way.  ;-)

Also keep in mind "emerge --resume" and "emerge --resume --skipfirst". 
The first is in case you have to stop to reboot or something.  The
second is in case something fails to emerge and you want to rebuild it
later.  Make a note of what packages fail and the error.  You may need
that info later.

Hope that helps.

What is the difference between Mechanical Engineers and Civil Engineers?
Mechanical Engineers build weapons, Civil Engineers build targets.

Yes, I think an "emerge --deep --emptytree world" would be in order.

If you had a recent backup of your system-- new enough that no new
packages had been emerged since the backup was taken-- then restoring
the backup would be the easiest option.

In this case, though, it seems like a reasonable tradeoff to wait for
all your packages to recompile in order to be more confident that your
system won't blow up on you.

Wow.  The other posters are right.  Re-emerging everything is a waste of
time.  It'd be much easier to re-emerge only the packages that had
placed files into /sbin .

Thanks, Geistteufel and Bo Andresen for reminding me of this!

Why? And what exactly do you expect --deep to do with --emptytree?

Using --deep is a force of habit for upgrades, so I'm inclined to type it 
all the time.  But you raise a good point: it has no effect on --emptytree 
world .
