HOWEVER, only install the second one if have already installed the Quircky Tahr 6.0.5 "devx" PET.
Note that Quirky maintains an audit trail of all changes to the
system, and even with a massive upgrade from Tahr 6.0.5 to Unicorn 6.2,
it should be possible to roll back to Tahr 6.0.5.
There are two ways to do it. The "safest" way is probably to take a
snapshot of the entire partition, prior to upgrading Tahr to Unicorn.
See menu Filesystem -> Snapshot Manager
The other way is that the Quirky Package Manager records all changed,
moved and deleted files when a new package is installed (in
/audit/deposed), which means that the package can be uninstalled and the
system restored to how it was before the package was installed.
In theory anyway. It remains to be seen if this will work with the
massive Tahr to Unicorn PET uninstallation -- though, even if someone
tries this and it fails, if you have also taken a snapshot (first method
described above), then that can be applied to rollback at bootup (in
syslinux.cfg or whatever, insert kernel boot parameter "qfix=bak"), even
with a broken system.
