Got a huge #git repo to clone you want to speed up? Do a quick first shallow clone, and perform an *unshallow* in the background!

Example with the Linux kernel source tree below.
```
# 234.24 MiB - ready in under a minute
$ git clone --depth 1 --branch v6.2 \
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

$ cd linux # start working!

# downloads remaining ~ 2.00 GiB
$ git fetch --unshallow
```
