+Default BASE_CODENAME is bullseye. Default ARCH is 64. The script expects corresponding
+$BASEFILE_DIR/${UPCASED_BASE_CODENAME}${ARCH}.tar.(gz|xz) to exist, and it must have been
+generated around the same time as the nfsroot, at least so it has the
+same kernel version.

+Note: there is a bug in 5.9.4, fixed by adding
+ sleep 2

+Note: in t9, there is a bug in recent fai packages (eg 2021+), where
+ unshare uses a too new argument. I was able to fix it by
+ just going to the site of the error and changing unshare to
+ chroot like it used to be, but I'm not bothering to make
+ any persistent fix, since I'm now on t10. If it ever came
+ up again, using an old fai package would also work.
