=head3 parseLiteFiles
|
|
In the liteentry table, one directory and its sub-items (including sub-directory and entries) can co-exist;
|
|
In order to handle such a scenario, one hash is generated to show the hirarachy relationship
|
|
|
|
For example, one array with entry names is used as the input:
|
|
my @entries = (
|
|
"imagename bind,persistent /var/",
|
|
"imagename bind /var/tmp/",
|
|
"imagename tmpfs,rw /root/",
|
|
"imagename tmpfs,rw /root/.bashrc",
|
|
"imagename tmpfs,rw /root/test/",
|
|
"imagename bind /etc/resolv.conf",
|
|
"imagename bind /var/run/"
|
|
);
|
|
Then, one hash will generated as:
|
|
%hashentries = {
|
|
'bind,persistent /var/' => [
|
|
'bind /var/tmp/',
|
|
'bind /var/run/'
|
|
],
|
|
'bind /etc/resolv.conf' => undef,
|
|
'tmpfs,rw /root/' => [
|
|
'tmpfs,rw /root/.bashrc',
|
|
'tmpfs,rw /root/test/'
|
|
]
|
|
};
|
|
|
|
Arguments:
|
|
one array with entrynames,
|
|
one hash to hold the entries parsed
|
|
|
|
Returns:
|
|
0 if sucucess
|
|
1 if fail
