The revisions listed as "adds" were already present in the repository and have only been added to this reference. Detailed log of new commits: commit 9322a0d3b7360f47339e98533a1bcbec321921f4 Author: Gerardo Exequiel Pozzi <vmlinuz386(a)gmail.com> Date: Tue Jan 27 14:37:05 2015 -0300 [archiso] Rename cowfile_size to cow_spacesize= The name is more relevant since the usage is shared for both dm-snapshot and overlayfs. Signed-off-by: Gerardo Exequiel Pozzi <vmlinuz386(a)gmail.com> commit a637bdb8574168ab4cddef13d5de7f458650bda5 Author: Gerardo Exequiel Pozzi <vmlinuz386(a)gmail.com> Date: Tue Jan 27 14:37:05 2015 -0300 [archiso] Add optional OverlayFS support This is the first attemp to test overlayfs in archiso. The current dm-snapshot mode is keep and is enabled by default, while the new mode is enabled via "-s sfs" to mkarchiso. No new boot parameters are added, since archiso hooks detects if the .sfs file is for dm-snapshot (airootfs.img inside) or for overlayfs. Persistence is supported in overlayfs mode using the same options (cowlabel or cowdevice), but warning while in dm-snapshot mode, only one file is used (airootfs.cow), in overlayfs mode internal files for workdir/ and upperdir/ are allocated, so you can not use VFAT or NTFS. To test this, you need to enable [testing] in pacman.conf from releng profile and edit build.sh then add "-s sfs" in make_prepare() Look at: setarch ${arch} mkarchiso ${verbose} -w "${work_dir}" -D "${install_dir}" prepare Replace with: setarch ${arch} mkarchiso ${verbose} -w "${work_dir}" -s sfs -D "${install_dir}" prepare The build requires just half of space that the build for dm-snapshot, since there is no ext4 img ;) Just to remember: there is no space gain in .sfs (just about 2M) There is at least one thing during boot with machine-id service: Dec 24 03:31:39 archiso systemd-machine-id-commit[183]: Failed to unmount transient /etc/machine-id file in our private namespace: Invalid argument Signed-off-by: Gerardo Exequiel Pozzi <vmlinuz386(a)gmail.com> Summary of changes: archiso/initcpio/hooks/archiso | 28 +++++++++++++++++++++------- archiso/initcpio/install/archiso | 1 + archiso/mkarchiso | 34 ++++++++++++++++++++++++++++++---- docs/README.bootparams | 14 ++++++++------ 4 files changed, 60 insertions(+), 17 deletions(-) -- To stop receiving notification emails like this one, please contact the administrator of this repository.
