Hello All,
I am using mfsbsd (https://github.com/mmatuska/mfsbsd) to create an ISO with some of my own custom changes in it. I wanted to keep memory disk mounted to / (root) and for storage I wanted to use zfs, on hardisk.
I tried following to achieve it with no success yet .i.e.
1.) created 3 partitions as below
.i.e boot, root(UFS) and storage (ZFS) ( device use here is of 16 GB)
2.) Keeping ISO mounted copied content from ISO to disk
3.) created zpool over partion 3 .i.e.
4.) Created zfs on storage Pool .i.e.
5.) copied zpool cache to disk boot folder
.i.e.
However when did the reboot( from hard-disk), zpool/zfs related changes does not persist.
in attempt 2 I have install zfsboot code
however it fails with giving error not able to find boot/zfsloader and /boot/loader
please guide me how to achieve persist mount points of zfs pools, in between reboots of an mfsbsd image
