NAME

       febootstrap-run - Run extra commands in febootstrap root filesystem

SYNOPSIS

        febootstrap-run [--options] DIR [--] [CMD ...]

DESCRIPTION

       This can be used to run extra commands in the febootstrap root
       filesystem.  It is just a simple wrapper around the standard "fakeroot"
       and "fakechroot" commands.

       If given, the "CMD ..." is run inside the root filesystem.  The command
       acts as if it was run as root and chrooted into the root filesystem.

       If the command is omitted, then we start a shell.

       If "CMD ..." could contain anything starting with a "-" character then
       use "--" to separate "febootstrap-run" parameters from the command:

        febootstrap-run ./f10 -- ls -l

OPTIONS

       --ro
           Usually any changes to permissions made by the command are recorded
           in the "fakeroot.log" file.  However if "--ro" flag is given, then
           changes to permissions are not recorded.  (Note: changes to file
           contents still happen).

EXAMPLES

       Remove a directory subtree safely:

        febootstrap-run initramfs -- rm -r /etc

       (This requires that you have a compatible ’rm’ command in the root).

       Another way to do complex operations from a script is to export a
       function:

        #!/bin/bash

        do_stuff ()
        {
            # complex operations inside the root
        }
        export -f do_stuff
        febootstrap-run root -- bash -c do_stuff

ENVIRONMENT VARIABLES

       Some fakechroot(1) environment variables are applicable.  In particular
       you may want to set:

        export FAKECHROOT_EXCLUDE_PATH=/proc
