Last night I did rm -Rf /tmp as root. I wasn't drunk. But I definitely feel I was dumb to do so. Now X doesn't work. I read few days back that after doing rm, one can't recover the lost data. I mounted a USB stick but it doesn't show up in /media directory. I need to backup the data in /home folder. I think I can recover that data by some live usb.

Is there a way to backup the rpms that are installed on Fedora machine? I wish to save bandwidth. So if it's possible, I'd prefer saving all the installed rpms in a directory and then re-installing them simply by doing rpm -i. I earlier posted this question but YUMonCD package doesn't work fine on my Fedora 14. I found this to create a list of installed rpms and then re-installing it after formating. But it doesn't save any bandwidth for me.

Just recreating the /tmp directory with proper permissions should do the trick.

mkdir /tmp
chmod 777 /tmp
chmod +t /tmp

/tmp does not contain any crucial data that needs to be kept intact between reboots, but it is crucial for quite a number of applications that the directory exists and can be written to.

Wow!!! You're the savior... Thanks a lot.. Can't express the gratefulness in words.. You saved me from formatting. – Dharmit Apr 11 '11 at 9:30

RPMs that are downloaded and installed by yum are stored in /var/cache/yum/<repo name> so just back up those directories if you need to.

EDIT: you have to set keepcache=1 in /etc/yum.comf if you don't want the downloaded rpms to be deleted after successful installation.

I think it's "yum.conf", not "yum.comf" – user7538 May 17 '11 at 6:26

There is a new version of yumoncd in this link http://sourceforge.net/projects/yumoncd/
