a strategy to manage hd & memory space ...

[mimosa]

I don't quite understand the problem with booting and xfs.

About the duplication, no problem there at all. Either mounting the partition as /usr will work, or not. In either case, the OS only sees one of the two identical usr directories.

The likely reasons for it not to work are

1) you copied it wrongly

2) your fstab entry is wrong

so if you hadn't reverted it, the next step would be to ask you to post your fstab and the result of

Code: Select all

ls /usr
mount

If, before changing anything else, you mount the partition somewhere and list the contents, the results should look exactly the same as for /usr.

You can also test without rebooting, see the links I posted above.

The live usb i had handy was a manjaro openrc pekwm - it lamented onboot the inernal hd was unreadable; i presumed because of a missing implementation of xfs utilities. A practical problem, when i booted from the internal hd, was: sudo & nano are in /usr/bin (not bin). I solved by using mv to rename back /usr-bac to /usr.

Ok. I'll try that in the next days - before i have to finish some teaching work and to prepare a really useful and working recover usb

You could try Salix Live - but make sure you read the instructions about how to put it on a USB stick.
