I'm using a frugal installation, not a traditional hard drive installation. I realize now that I should have made that clearer.

OK, I see now that the /ramdisk/home/dsl and /mnt/hda3/home/dsl directories are mirrors of each other - anything I do in one of these two directories automatically translates into a duplicate change in the other directory. What made this possible? Is it the home=hda3 cheat code, the restore=hda3 cheat code, or something else?

Is there a way to make /ramdisk/home/<username> and /mnt/hda3/home/<username> also behave as mirrors of each other?

You are NOT using a frugal. You are using a hybrid.

A frugal installation operates the same as a live CD. A frugal operates like the live CD in that it does not anchor any user files to the hard drive during normal operation.

A hybrid, is frugal plus the option of specifying a persistent /home and/or a persistent /opt. These additionaly options are not required and are not normally used. They are made available for those wishing such feature. For some having anchored directories is fine.

Please keep these terms clear as it can get confusing.

I see you have a backup/restore on the same drive/partition. If this device should fail you lose both. When using the optional persistent home the backup should idealy be on a different drive.

The 'mirror' as you put it, is really a 'bind'. The bind, binds together the ramdisk default with the anchored directory. There would be no need for an additional bind as there are no further home directories defaulting to the ramdisk. As the live CD/frugal is not multiuser.

Tyring to shoe horn multiusers into a hybrid will still present many challenges as the extension library is made for user dsl.

What is the difference between the backup and restore cheat codes? I see now that if I use both functions, they should be on different drives or at least different partitions.

I see now that frugal/hybrid installations are not compatible with multiuser format and instead should be thought of as having user dsl.
