An ultility python script helps me enter my chroot environment easier

enter_doanything.py

import subprocess
import argparse


def log(msg):
    print('# {msg}'.format(msg=msg))

def loghr(msg):
    print(72 * '#')
    log(msg)

def disable_display_access_control():
    loghr('disable display access control')

    cmd = 'xhost +'
    log(cmd)

    subprocess.check_call(cmd, shell=True)

def enter_chroot_env():
    loghr('enter chroot environment')

    cmd = 'sudo uck-remaster-chroot-rootfs /home/vu/work/devenv/doanything'
    log(cmd)

    subprocess.call(cmd, shell=True)

def mount(dirs):
    if dirs is None:
        return
    
    dirs = dirs.split(',')

    for dir in dirs:
        loghr('mount {dir}'.format(dir=dir))

        cmd = 'sudo mkdir /home/vu/work/devenv/doanything/remaster-root/media/{dir}'.format(dir=dir)
        log(cmd)
        subprocess.call(cmd, shell=True)

        cmd = 'sudo mount --bind /home/vu/work/{dir} /home/vu/work/devenv/doanything/remaster-root/media/{dir}'.format(dir=dir)
        log(cmd)
        subprocess.check_call(cmd, shell=True)

    args = argparser.parse_args()
