=head1 NAME
|
|
|
|
B<liteimg> - Modify statelite image by creating a series of links.
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
I<liteimg [-h| --help]>
|
|
|
|
I<liteimg [-v| --version]>
|
|
|
|
I<liteimg imagename>
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
This command modifies the statelite image by creating a series of links.
|
|
It creates 2 levels of indirection so that files can be modified while in
|
|
their image state as well as during runtime. For example, a file like
|
|
<$imgroot>/etc/ntp.conf will have the following operations done to it:
|
|
|
|
I< mkdir -p $imgroot/.default/etc>
|
|
|
|
I< mkdir -p $imgroot/.statelite/tmpfs/etc>
|
|
|
|
I< mv $imgroot/etc/ntp.conf $imgroot/.default/etc>
|
|
|
|
I< cd $imgroot/.statelite/tmpfs/etc>
|
|
|
|
I< ln -sf ../../../.default/etc/ntp.conf .>
|
|
|
|
I< cd $imgroot/etc>
|
|
|
|
I< ln -sf ../.statelite/tmpfs/etc/ntp.conf .>
|
|
|
|
|
|
When finished, the original file will reside in
|
|
I<$imgroot/.default/etc/ntp.conf>. I<$imgroot/etc/ntp.conf> will link to
|
|
I<$imgroot/.statelite/tmpfs/etc/ntp.conf> which will in turn link to
|
|
I<$imgroot/.default/etc/ntp.conf>
|
|
|
|
Note: If you make any changes to your litefile table after running liteimg then you will need to rerun liteimg again.
|
|
|
|
