dd-multi.sh: add --keep-files

2019-04-26T13:00:20Z

The first couple steps of the dd-multi.sh script is to: 1. make a sparse copy of the original image 2. loop mount the copy 3. unpack the layers to the loop mount 4. create a vmdk of the copy 5. copy the image and vmdk to the usb drives If many USB drives need to be prepared at once, usually the dd-multi.sh script will need to be called multiple times (due to not enough USB-3 ports being available). However, there is no need for steps 1-4 to run each time. Add a --keep-files argument that will not delete the copy and vmdk files on completion. The --keep-files argument also tells the dd-multi.sh script to look for existing copy and vmdk files. If they are found, they are used. Signed-off-by: John Ogness

dd-multi.sh: inform the trainer how much to dd

2019-04-09T13:53:52Z

The dd step is the longest, so showing the progress is nice. But dd does not show how big the file is. Hard-code the size since we know how big it is. Signed-off-by: John Ogness

dd-multi.sh: use dd features from stretch and 128M blocks

2019-04-09T13:48:18Z

All trainers are now using stretch (or higher), so use the status=progress feature. Also, increase the blocksize to 128M since that amount should be available on the cloning host. Signed-off-by: John Ogness

lx-trainer-vm: add linaro aarch64 toolchain

2019-04-09T12:14:05Z

Add the aarch64 toolchain from linaro. Use the same version as the armhf toolchain: 6.3.1-2017.05. Signed-off-by: John Ogness

lx-trainer-vm: set preseed for man-db

2019-04-09T12:05:17Z

If the man-db preseed is not set, the man database is not created by elbe. This means that things like: man -k timer won't work. Preceed the configuration so that the database exists immediately. Signed-off-by: John Ogness

lx-trainer-vm: add kernel debugging symbols

2019-02-28T14:01:09Z

This is useful when demonstrating crash kernels with the Debian kernel. Signed-off-by: John Ogness

lx-trainer-vm: add required preseeding for jackd2

2019-02-28T13:59:51Z

When installing jackd2, it is required that the user choose if realtime options are allowed. Say "yes" in the preseeding. Signed-off-by: John Ogness

lx-trainer-vm: add debconf-utils

2019-02-25T13:25:36Z

It is nice to have debconf-get-selections so that the preseeding values can be investigated. Signed-off-by: John Ogness

lx-trainer-vm: install lots of new packages

2019-02-25T12:06:07Z

(helps for a comfortable vmware experience) open-vm-tools-desktop (requested from training participants) vim-gtk3 terminator iotop bash-completion (compression tools for building LZ4-compressed kernel/initramfs) liblz4-tool (realtime stress testing) stress-ng (fastboot tool) prelink (tool for devel/debugging) clang (packages for building new kernelshark) tig cmake libjson-c-dev freeglut3-dev libxmu-dev libxi-dev Signed-off-by: John Ogness

lx-trainer-vm: add manpages from stretch-backports

2019-02-15T16:16:02Z

With commit 80aaf492("lx-trainer-vm: take manpages from stretch-backports"), elbe was no longer able to build the rootfs because manpages-dev also requires manpages from backports. Signed-off-by: John Ogness
