2020-10-12Change btfrs uuid all the timeAndrew Cady
This is a workaround for a kernel bug that happens when you try to mount the image file after creating it with cp. It acts as if the same UUID is already mounted, even though it isn't (anymore). Changing the UUID on the image allows mounting it. Can't use 'btrfstune -m' here because (for the time being) it doesn't work on seed images. So that means that the operation is slow. It is done more than necessary because it is done wherever made necessary by existing code. TODO: Change the actual behavior of the program to wait until the very end to set seed property. Only set -S1 when creating the patchfs or creating the uplevel image.

2020-05-30Do not hardcode "stretch"Andrew Cady
Instead, get codename (used to determine versions for all the packages) from '/etc/os-release' This should be specifiable (and inherited) in the yaml config file too. The *.devices mechanism shows the need to create inheritable "settings." Perhaps they should be in Haskell not through the filesystem.

2020-05-28Begin support for "seeded images."Andrew Cady
A seeded image keeps its parent image as a read-only "seed" device that joins the seeded image in a multi-device btrfs filesystem. That means that to mount such an image, the parent image must be made available as a block device (e.g. using losetup, or dd to an existing block device and run btfrs device scan). Such support had been added to the Samizdat Makefile, but more properly belongs here. This is the sequence of commands used by sami.git's Makefile to accomplish the effect: rm -f $@~tmp touch $@~tmp fallocate -l $(samizdat_btrfs_patch_size) $@~tmp test -d $@.mnt || mkdir $@.mnt ! mountpoint -q $@.mnt || umount $@.mnt mount -o compress,ro -t btrfs $< $@.mnt a=$(get_loop_dev); [ -z "$$a" ] || losetup -d $$a losetup -f $@~tmp btrfs device add $(get_loop_dev) $@.mnt mount -o compress,rw,remount $@.mnt The Makefile also defines: get_loop_dev="$$(sudo losetup -n -O name -j $@~tmp)" The same basic sequence is carried out here. The config file format is modified so that to get a seeded image you specify "seedme: <bytes>" where <bytes> is the size of the seeded image. This feature is complete enough to create a seeded image (i.e., to replace the Makefile), but children of a seeded image seem impossible to work because there is no code yet to run losetup on seed images of parents. Thus it can be expected that deriving from a parent with a seed will fail when fsmgr tries to mount the parent.
