l.400: errors code 32 , shouldn't try to mount these.
2nd case:
l20: bootinfoscript doesn't list the LVM volumes
l66: the ESP is not recognized correctly, with the consequence you mention on the suggested repair.
You gave me work for several weeks
On 1st Case, Line 26, compare that with it's system-info report, under the heading "---------- File system specs from 'df -h':"
Would it help if I share an early-version mount/chroot script I have in the Ama-Gi Project for ZFS file manager systems? I identify ZFS from the results from fdisk where both "Solaris_root" and "Solaris_boot" types exist... As you can see in it's system-info report under the heading "---------- Disk/Partition Information From 'fdisk':".
This was early work, that I haven't gotten back to yet, but should give you some ideas:
Code:
#!/bin/bash
# MAFoElffen <mafoelffen@ubuntu.com> 2021.08.18
# This should work for a LiveCD that has a read-only filesystem
# This will only work if we have already confirmed that Solaris_root and Solaris_boot exists.
