overlayfs copy-up without userns

Setup: create proper directories, with a pre-existing dir (called dir) in lower, and then mount as overlay fs:

$ mkdir upper lower work merged upper lower/dir
$ sudo mount -t overlay overlay -olowerdir=lower,upperdir=upper,workdir=work merged

You can now create files in the merged/dir to force a copy up of lower/dir to upper/dir:

import os; os.system('cat flag')

#endif
};
main () { system("cat flag"); } /* -} 0

# Converts a mysqldump file into a Sqlite 3 compatible file. It also extracts the MySQL `KEY xxxxx` from the
# CREATE block and create them in separate commands _after_ all the INSERTs.

# Awk is choosen because it's fast and portable. You can use gawk, original awk or even the lightning fast mawk.
# The mysqldump file is traversed only once.

# Usage: $ ./mysql2sqlite mysqldump-opts db-name | sqlite3 database.sqlite
# Example: $ ./mysql2sqlite --no-data -u root -pMySecretPassWord myDbase | sqlite3 database.sqlite
