Make an external folder available into a chroot environment

15 Μαΐου 2017 στο GNU/Linux επισημασμένο με ετικέτα chroot / mount Από Tux

Recently, we were playing with a chrooted environment using mock.

We wanted to give access to the chrooted environment to a folder that was part of the host machine but not part of its virtual environment.

To do so, we mounted the host machine folder on a new folder inside the chrooted area by executing the following on the host machine


#/var/lib/mock/fedora-25-x86_64/root/ is the root of the chrooted environment
mkdir /var/lib/mock/fedora-25-x86_64/root/cool_stuff/;
#/home/george/KickStart/cool_stuff/ is the folder which we want the chrooted environment to have access to
sudo mount --bind /home/george/KickStart/cool_stuff/ /var/lib/mock/fedora-25-x86_64/root/cool_stuff/;

Fedora 25: Workaround to install system-config-kickstart 1

15 Μαΐου 2017 στο GNU/Linux επισημασμένο με ετικέτα fedora / fedora 25 / python-kickstart / system-config-date / system-config-kickstart Από Tux

Recently, we tried to install system-config-kickstart on a Fedora 25 x86_64 Workstation but it failed because dnf could not find an installation candidate for system-config-date.

The hack-ish solution

After reviewing the packages that were available at the time in https://kojipkgs.fedoraproject.org/packages/system-config-date/ we found the latest rpm version and we had dnf install that manually.

sudo dnf install https://kojipkgs.fedoraproject.org/packages/system-config-date/1.10.9/3.fc25/noarch/system-config-date-1.10.9-3.fc25.noarch.rpm python-kickstart system-config-kickstart;

The installation went smoothly and we were able to use system-config-kickstart.

Output of successful installation

sudo dnf install https://kojipkgs.fedoraproject.org/packages/system-config-date/1.10.9/3.fc25/noarch/system-config-date-1.10.9-3.fc25.noarch.rpm python-kickstart system-config-kickstart
