Top Forums UNIX for Beginners Questions & Answers Iso - remaster script trying to start chroot run commands then exit but host system gets messed up Post 303039788 by Corona688 on Tuesday 15th of October 2019 01:19:42 PM

Sorry, my morning coffee hadn't kicked in.

Your chroot commands get things ready for a chroot, but don't actually run chroot, so nothing ends up happening inside the chroot.

If you call chroot the way I show it
Code:
chroot /path/to/folder /path/to/shell < inputfile

...it ought to finish by itself when it hits end-of-file. Interactive commands may foul this up.

So,
Code:
chrootbeg
chroot /path/to/folder /path/to/shell < /path/to/inside-chroot-script
chrootend

chroot

CHROOT(8)						    BSD System Manager's Manual 						 CHROOT(8)

NAME

     chroot -- change root directory

SYNOPSIS

     chroot [-G group,group,...] [-g group] [-u user] newroot [command]

DESCRIPTION

     The chroot command changes its root directory to the supplied directory newroot and exec's command, or, if not supplied, an interactive copy
     of your shell.

     If the -u, -g, or -G options are given, the user, group, and group list of the process are set to these values after the chroot has taken
     place; see setgid(2), setgroups(2), setuid(2), getgrnam(3), and getpwnam(3).

     Note: command or the shell are run as your real-user-id.

ENVIRONMENT

     The following environment variable is referenced by chroot:

     SHELL  If set, the string specified by SHELL is interpreted as the name of the shell to exec.  If the variable SHELL is not set, /bin/sh is
	    used.

SEE ALSO

     ldd(1), chdir(2), chroot(2), environ(7)

HISTORY

     The chroot utility first appeared in 4.4BSD.

SECURITY CONSIDERATIONS

     chroot should never be installed setuid root, as it would then be possible to exploit the program to gain root privileges.
