*If you are running the script from the containing folder (first install method) please make sure you use the `./mkstage4.sh` command instead of just `mkstage4`!*
Note that the extension will automatically be appended to the `archive_name` string based on the compression type, which can be specifiled via the `-C` parameter, if another compression than the default (`.tar.bz2`) is desired.
### Examples
Archive your current system (mounted at /):
```bash

### Command line arguments
```console
mkstage4.sh [-q -c -b -l -k -p] [-s || -t <target-mountpoint>] [-e <additional excludes dir*>] <archive-filename> [custom-tar-options]
-q: activates quiet mode (no confirmation).
-c: excludes connman network lists.
-b: excludes boot directory.
-l: excludes lost+found directory.
-p: compresses parallelly using pbzip2.
-e: an additional excludes directory (one dir one -e).
-s: makes tarball of current system.
-k: separately save current kernel modules and src (creates smaller archives and saves decompression time).
-t: makes tarball of system located at the <target-mountpoint>.
-C: specify tar compression (shows available on runtime and default is bz2)
-h: displays help message.
usage:
mkstage4 [-q -c -b -l -k] [-s || -t <target-mountpoint>] [-e <additional excludes dir*>] [-i <additional include target>] <archive-filename> [custom-tar-options]
-q: activates quiet mode (no confirmation).
-c: excludes some confidential files (currently only .bash_history and connman network lists).
-b: excludes boot directory.
-l: excludes lost+found directory.
-e: an additional excludes directory (one dir one -e, donot use it with *).
-i: an additional target to include. This has higher precedence than -e, -t, and -s.
-s: makes tarball of current system.
-k: separately save current kernel modules and src (creates smaller archives and saves decompression time).
-t: makes tarball of system located at the <target-mountpoint>.
-C: specify tar compression (default: bz2, available: lz4 xz bz2 zst gz).
-h: displays help message.
