I've deleted /bin by mistake. Now I can't boot my Slackware64 13 system.


Well, as the title says, I deleted /bin by mistake. I wanted to remove a bin folder that was in a backup partition and I think I used rm -r /bin as root instead of rm -r bin (this happens when one is tired and needs some sleep :-).

From there on, terminal did not recognize commands. I didn't realized what happened until I rebooted my computer and it stopped loading and, of course, there isn't any prompt nor X.

So, before I start to cry :-( Is there something I can do to recover my /bin folder and Slackware64 13?

Now, I can write this thread because I am running Debian Lenny. I can also mount Slackware partitions from here. Advantages of using more than a Linux OS.

Thanks my friends!

Do you still have the Slack install disk? I think it is a live-CD, so you could boot from it and copy /bin to your Slack partition.

Yes, I have it but I am not sure it is a livedvd. Is it possible to copy the /bin folder to my slackware partition but from Debian (which I am using now)?

If that is possible, Do I have just to copy it as root or I have to do something else? Where is /bin in the Slackware DVD?

I also have partedmagic livecd.


Thanks for your help. I keep listening...

If you have a backup of /bin at hand, just copy it to / -- but I guess you don't so AFAIK all you can do is reinstall, not forgetting backup directories containing files that you wish to keep, at least /home (if you need to re-format the partition where it lives), /etc and maybe /var (e.g. for databases files).

I don't think coping /bin from Debian will work, even if Debian is the 64-bit version. It may even make things worse.

From Debian you could mount the Slack install disk (or the iso file) and look to see if their is /bin on the disk that you can copy.

No, I don't have any /bin backup :-(

And...What about the packages I've installed? Will I have to reinstall them?

My partition scheme in slackware is:

/
/home
SWAP

I didn't mean to copy /bin from Debian to Slackware. What I was trying to say was if I could copy /bin from the slacware dvd to /bin in slackware root partition but using debian to copy those files. But, as far as I can see, there isn't any /bin folder in slackware dvd.

Is there a way to backup my installed packages?

Thanks for your cooperation.

I didn't see your last message before posting.

Do not copy /bin from Debian, if you do Slackware won't work for long after that.

And there is no /bin directory available on you installation disk, it is created by the installer on your disk drive.

I answer to your last post.

Yes, you'll have to reinstall all your Slackware packages.

No big deal if you did a full install, its a matter of 15-20 minutes or so on your machine.

Thanks Didier! What about the packages I've installed after installing Slackware (openoffice and so many others). Do I have to reinstall them too?

I will copy my /tmp folder. That way I may reinstall those packages with

installpkg *.t?z.

I will also copy /etc and /var. Since /home is on a different partition, I wont reformat it when reinstalling. Do I have to backup anything else?

Thanks again,

Germán.-

You will possibly not have to install your packages if they installed to /usr/bin, but be prepared to install them if they don't work. If you just go to the slackware directory on your cd and you will see a, d, e, f .... etc and run

upgradepkg --reinstall */*.t?z

that should look at /var/log/packages and only install the packages that you have installed on your system. This is useful if, like me, you trim your install.

Yes, you will have to reinstall all packages, be it included or not in the distribution, as all directories but /home will have to be formatted during setup.

If you installed some packages in /opt (e.g. this could be the case for OpenOffice and Adobe Reader), you could backup their directories. But then you will have to re-create the symbolic links to it after having copied it to the new system, so I'm not sure this is worth the hassle. All in all I think you'll be better off reinstalling everything, to make sure you have a clean system.

Then if you happen to build yourself a package, e.g. using the slackbuilds available at http://slackbuilds.org, keep the package after installing it just in case.

Chances that you have to reinstall your custom compiled packages are low. That depends of course on which packages exactly that are, but on my system I don't have a single (of many custom compiled) package which saves a file in /bin.

If you are not sure and if you can identify the packages (by a special tag or something) you can check that. For example to look for all packages build by script from Slackbuilds.org:
Code:
grep -e "^bin" /var/log/packages/*SBo*
grep -e "^bin" /var/log/scripts/*SBo*

You really will not have to re-install your entire system. Just boot your computer using the install cd/dvd and then follow the instructions in my previous post, and all your settings will be intact.

Do what samac says

What came to my mind in addition: After reinstalling all apps you will probably have some ".new" files let's say in /etc. Be sure to search for them (find /etc -type -f -name "*.new"), merge eventually made changes and remove the duplicate files.
