=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
