Hi,
I check this morning, dm-snapshot.ko was yet included in initrd as show
by lsinitrd.
$ lsinitrd /boot/initramfs-3.10.0-1127.18.2.el7.x86_64.img | grep
dm-snapshot.ko
-rw-r--r-- 1 root root 20372 Jul 26 17:38
usr/lib/modules/3.10.0-1127.18.2.el7.x86_64/kernel/drivers/md/dm-snapshot.ko.xz
I've rebuilt the image this morning (dracut -fv) with the snapshot "on"
and I'll try a reboot next week (I work remotely these next days).
An important thing is that during the kernel update (and initrd build
for the new kernel), the snapshot was also available.
