This package should never be installed in an already running system! It should only be selected by a system role for a read-only root filesystem with transactional updates. The package will create / modify entries for mounting /etc and /var. Those entries are used by dracut to mount the overlay file systems during the early boot phase. %package volatile Summary: Dracut Module to mount a tmpfs overlay on a RO root Group: System/Fhs Requires: dracut %description volatile A dracut module which mounts an overlayfs each on /etc and /var, with the upper layer in a tmpfs mount. This is the minimal setup to get a booting system, to have a writable /root or /home, additional fstab entries can be added. %prep %setup -q %build %install cp -a etc usr %{buildroot} mkdir -p %{buildroot}%{_localstatedir}/lib/overlay/work-etc %post if [ "$1" = 1 ] ; then %{_sbindir}/setup-fstab-for-overlayfs mkdir -p %{_localstatedir}/lib/overlay/1/etc fi if [ ! -e /boot/writable -a "`findmnt -n -o FSTYPE -l /`" = "btrfs" ]; then %{_sbindir}/mksubvolume /boot/writable fi %{?update_bootloader_refresh_post} %posttrans if [ -f %{_sysconfdir}/zypp/zypp.conf ]; then sed -i 's/^multiversion =.*/multiversion =/g' %{_sysconfdir}/zypp/zypp.conf fi # btrfsmaintainence uses as default "/", but that is read-only. # Change that to /.snapshots/ for var in BTRFS_BALANCE_MOUNTPOINTS BTRFS_SCRUB_MOUNTPOINTS BTRFS_TRIM_MOUNTPOINTS; do grep -q "${var}=\"/\"" /etc/sysconfig/btrfsmaintenance && sed -i "s|${var}=.*|${var}=\"/.snapshots\"|g" /etc/sysconfig/btrfsmaintenance done %{?update_bootloader_posttrans} exit 0 %files %license COPYING %{_sbindir}/setup-fstab-for-overlayfs %{_localstatedir}/lib/overlay %{_prefix}/lib/dracut/dracut.conf.d/10-read-only-root-fs.conf %{_prefix}/lib/systemd/system-preset/* %dir %{_prefix}/lib/systemd/system/systemd-udevd.service.d %{_prefix}/lib/systemd/system/systemd-udevd.service.d/etcmount.conf %dir %{_prefix}/lib/systemd/system/systemd-journal-flush.service.d %{_prefix}/lib/systemd/system/systemd-journal-flush.service.d/afterlocalfs.conf %dir %{_prefix}/lib/systemd/system/systemd-remount-fs.service.d %{_prefix}/lib/systemd/system/systemd-remount-fs.service.d/writableagain.conf %dir %{_sysconfdir}/grub.d %config(noreplace) %{_sysconfdir}/grub.d/01_suse_ro_root %files volatile %license COPYING %{_prefix}/lib/dracut/modules.d/99volatile-overlay/ %changelog
