=head1 NAME
febootstrap-run - Run extra commands in febootstrap root filesystem
=head1 SYNOPSIS
febootstrap-run [--options] DIR [--] [CMD ...]
=head1 DESCRIPTION
This can be used to run extra commands in the febootstrap root
filesystem. It is just a simple wrapper around the standard
C<fakeroot> and C<fakechroot> commands.
If given, the C<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 C<CMD ...> could contain anything starting with a C<-> character
then use C<--> to separate C<febootstrap-run> parameters from the
command:
febootstrap-run ./f10 -- ls -l
=head1 OPTIONS
=over 4
=item B<--ro>
Usually any changes to permissions made by the command are recorded in
the C<fakeroot.log> file. However if C<--ro> flag is given, then
changes to permissions are not recorded. (Note: changes to file
contents still happen).
=back
=head1 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
=head1 ENVIRONMENT VARIABLES
Some L<fakechroot(1)> environment variables are applicable. In
particular you may want to set:
export FAKECHROOT_EXCLUDE_PATH=/proc
