Closes: #778497; new funcions in common.sh: - canonpath(): clean field separators in an arbitrary filepath - is_overlay_mountpoint(): grep /proc/mounts for 'overlay' filesystem - overlay_mountpoints(): doing the same as aufs_mountpoints() - overlay_lowerdir(): output the cleaned value of lowerdir= mount option - overlay_upperdir(): output the cleaned value of upperdir= mount option - overlay_workdir() - underlying_device_from_overlayfs(): find the underlying device from the 'lowerdir' value; fallback to live-boot (5.0~a1-1) usecases. Also modify underlying_device_from_file() to call the previous one. * bilibop-common: add support for btrfs. A file on a btrfs mountpoint is not directly mapped to the underlying block device: 'stat -c %D FILE' shows that the file seems to be on some kind of ramfs (major=0). So add two functions in common.sh: - is_btrfs_mountpoint() - underlying_device_from_btrfs() Also modify underlying_device_from_file() to call the previous one. * bilibop-common: modify other functions in common.sh: - underlying_device_from_aufs(): do not fail if the underlying device contains btrfs; now use aufs_readonly_branch() instead of aufs_dirs(), and call underlying_device_from_file() if the major number of the underlying device is 0 (be aware of a possible endless loop) - aufs_dirs(), aufs_readonly_branch() and aufs_writable_branch(): replace occurencies of glob pattern 'br*' by 'br?' to skip brid[01] files - underlying_device_from_file(), do not return 1 too early; let the last test say if the funcion failed or not - underlying_device_from_loop(): for the case the backing file itself is on btrfs, aufs or overlay, i.e. call underlying_device_from_file() from there too - find_mountpoint() and device_id_of_file(): to work around overlayfs specific design (files and dirs are not treated the same way) - underlying_device(): remove unneeded local variable assignment * bilibop-common: update copyright, README section and physical_hard_disk() dependency tree in common.sh * bilibop-common: update README.Debian, bilibop(7) and bilibop.conf(5). . * bilibop-lockfs: add support for overlayfs. - Modify local-bottom/bilibop-lockfs initramfs script: define $METHOD as the aufs or overlay module that is supported by the kernel, and use its value to setup specific mount options and mount points. Allow one to override the default directory name by setting BILIBOP_LOCKFS_PATH_PREFIX - Modify initramfs hook (+ manual_add_module overlay) Improve the part of the script related to mount commands (mount -t tmpfs, mount -o bind, mount -o move, ...). Make sure the paths of the branches used to build the union fs will be consistent at runtime (for both overlay, and aufs with brs=0), as the only one places to get those paths (e.g. mount options field in /proc/mounts) is out of sync. - Rewrite lockfs_mount_helper script, according to the initramfs script; prepare directory trees and add/modify comments. Change mount order; now the tmpfs mountpoint is set BEFORE the readonly branch, the last one being, by design (bilibop), a subdirectory of the first one. Introduce a new tunable variable BILIBOP_LOCKFS_PATH_SCHEME to choose the directory structure of the lower and upper branches. - Also modify lockfs-notify accordingly to support overlay filesystem * bilibop-lockfs: modify blacklist_bilibop_devices() in lockfs.sh. Manually add lvm-pv-uuid-* symlink to the list, as the udev rules creating it are not included into the initramdisk. * bilibop-lockfs: update README.Debian and lockfs_mount_helper(8) . * bilibop-rules: modify initramfs script. The busybox's readlink implementation does not work as expected (with -f flag) and does not resolve the target of a broken symlink; so replace the readlink call by a 'ls -l | sed' command. * bilibop-rules: modify lsbilibop. Remove '\n' in echo, as it is not supported by all shells, and call echo again to print an empty line (closes: #772187). * bilibop-rules: update lsbilibop(8) . * bilibop-udev: update README.Debian . * debian/control: bump Standards-Version to 3.9.6 (no changes needed). Update extended descriptions. * debian: modify bilibop-{lockfs,rules}.post{inst,rm}: use 'which' to test availability of update-initramfs command instead of testing its full path, to avoid a lintian warning.
