System and Network configuration • Re: migrating `/` and `/home` to a new (prior) device

Thanks again for your responses. So far no luck. Many adventures in `grub >` and `(initramfs)`, but the changes I made in the 3 files failed to produce a bootable system.



Root and efi

Code:

bashlsblkNAME   MAJ:MIN RM   SIZE RO TYPE MOUNTPOINTSsda      8:0    0 465.8G  0 disk ├─sda1   8:1    0   285M  0 part /boot/efi├─sda2   8:2    0  16.1G  0 part └─sda3   8:3    0 449.4G  0 part /home

1. First I `rsync` everything (that is `/` and `/home`) on `/dev/sda3` to `/dev/sda2`

Code:

sudo mount /dev/sda2 /mnt/d_sda2sudo rsync -ahPHAXx --delete --exclude={"/boot","/dev/*","/proc/*","/sys/*","/tmp/*","/run/*","/mnt/*","/media/*","/swapfile","/lost+found"} / /mnt/d_sda2

Note this doesn't include the `/boot` directory which resides on `/dev/sda1`


4. update `/etc/fstab` from,

Code:

cat /etc/fstab# <file system> <mount point>   <type>  <options>       <dump>  <pass># / was on /dev/sda3 during installationUUID=b7bdceb4-660a-4951-94cd-df9412b74f93 /               btrfs   rw,noatime,space_cache=v2,compress=zstd,ssd,discard=async,subvol=@ 0       0UUID=b7bdceb4-660a-4951-94cd-df9412b74f93 /home           btrfs   rw,noatime,space_cache=v2,compress=zstd,ssd,discard=async,subvol=@home 0       0# /boot/efi was on /dev/sda1 during installationUUID=C0E2-7937  /boot/efi       vfat    umask=0077      0       1/dev/sr0        /media/cdrom0   udf,iso9660 user,noauto     0       0

to

Code:

# <file system> <mount point>   <type>  <options>       <dump>  <pass># / was on /dev/sda3 during installationUUID=e042a944-8efa-4772-b46e-a24b878b4f7e /               btrfs   rw,noatime,space_cache=v2,compress=zstd,ssd,discard=async,subvol=@ 0       0UUID=e042a944-8efa-4772-b46e-a24b878b4f7e /home           btrfs   rw,noatime,space_cache=v2,compress=zstd,ssd,discard=async,subvol=@home 0       0# /boot/efi was on /dev/sda1 during installationUUID=C0E2-7937  /boot/efi       vfat    umask=0077      0       1/dev/sr0        /media/cdrom0   udf,iso9660 user,noauto     0       0

5. reboot... which lands me in the `grub>` prompt

No idea what I'm missing.

Thanks again,
