Chroot build environment
Working on this as I build a new virtual machine for semi-automated Linux and Windows builds.
Chroot
Our "weekly" builds are done in a virtual machine with a chroot prison for 32 and 64 bit builds and wine for the Windows build. Here I document step by step how to set one up. I write this as I go, so it is incomplete.
Make snapshots after every section or so.
Base system
Install Ubuntu Trusty in a virtual machine. Straightforward :) Pick LVM in the setup options so you can resize partitions later.
Install bzr and (optinal, I use it for remote access) ssh and stuff:
sudo apt-get update sudo apt-get install bzr ssh schroot
Add common volume to host builds
Use LVM to add a new volume. My VM has 150 G total space:
lvcreate -L 100G -n builds ubuntu-vg mkfs.ext4 /dev/ubuntu-vg/builds
If there is not enough space, reduce existing volumes. This needs to be done from a Live CD:
resize2fs /dev/ubuntu-vg/root 50G lvresize /dev/ubuntu-vg/root 50G
Add the new volume to fstab:
/dev/mapper/ubuntu--vg-builds /mnt/builds ext4 errors=remount-ro 0 1
This new volume will be mounted into the chroots for easy access.
