Creating the Build User

During the creation of the build environment, a non-privileged user other than root should be used for most tasks. When something calls for elevated privileges, the sudo command will be used to elevate rights to the superuser account. To simplify and standardize the build process for MidgardOS, run the following command to create the non-privileged builder user:

Note: if you are hosting the build from Fedora Linux, you might run into an issue where useradd will fail to properly create the user due to an issue with generating the /etc/subuid or /etc/subgid entry. To work around this, move the /etc/subuid and /etc/subgid files before creating the users, and put them back after creating the user.

groupadd -g 1001 -f build
useradd -u 1001 -s /bin/bash -g build -d /home/builder -c "MidgardOS build user" -M -N builder
install -v -d -m 755 -o builder -g build /home/builder

Grant Full Permission Rights to the tools and cross-tools Trees

To allow the builder user to have full rights to the sources, tools, and cross-tools directory trees, run the following commands:

setfacl -m u:builder:rwx /MidgardOS/sources
setfacl -m u:builder:rwx /MidgardOS/tools
setfacl -m u:builder:rwx /MidgardOS/{etc,usr,usr/{bin,include,lib,lib64,sbin,share},var/lib}

To make downloading sources and patches easier during initial builds, it is recommended to create a symbolic link from /MidgardOS/sources in the builder user home directory, like so:

ln -sv /MidgardOS/sources ~builder/sources
