# Alpine Chroot
### Installation
To create a base alpine chroot on any alpine system, run:
```sh
chmod +x *.sh
./alpine_init.sh
```
But this is assuming your current working directory is the directory of the
cloned repository.
Assuming your current working directory is the directory of the cloned repository.
When it is your first time in the chroot, run:
```sh
./chroot_init.sh
```
### Usage
Most people will go "into" the chroot via:
```sh
chroot /mnt/chroot sh
```
But you must remember that you can just as well run any program in the chroot
as:
```sh
chroot /mnt/chroot <program>
```
Because **chroots are not jails, containers, or sandboxes**. They simply change
what the system sees as the "root" point of the file system.
