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
