This configures automated installation using the subiquity installer, as
documented at
https://ubuntu.com/server/docs/install/autoinstall-quickstart and other
locations on the Internet.
Installation uses the NFS export of /install, and configures the
installer to use the nocloud-net datasource, creating a per-node
directory containing the processed template file as the user-data file,
and an empty meta-data file.
Kernel and initrd files are pulled from the casper/ directory under the
package dir.
Unnecessary elements of the kernel command line have been removed in the
subiquity installer path.
Support has been added for selecting a subiquity specific default
template, as well as an updated pre-install script and some minor POSIX
shell compliance fixes for the getinstdisk script.
- URL for kernel/initrd, get the value from below value tftpserver -> xcatmaster -> myipfn
- URL for image, get the value from below value nfsserver -> tftpserver -> xcatmaster -> myipfn
This patch refactor the interface to get xcatmaster and tftpserver
attributes in the subvars subroutine to improve the performance.
partial-issue: #3958
With the nytprof tool, the buttleneck is the time to update the bootparams
table.To optimize the performance on large scale nodes, this patch tranfer
the bootparams hash through variable reference.
posible impact: getdestiny can not get the information about bootparams.
partial-issue: #2024
directories, the last one was being used. However, the first one
on the list should be used per man page:
"The first path in the value of osimage.pkgdir must be
the OS base pkg dir path,..."
Fixing to use the first directory specified.
Also fixed a bunch for formatting, space, tab issues...
For sles.pm, clean up the $path variable to remove multiple slash
and trailing slash.
In debian.pm , move the check for -p and -w further down so it does
not appear unless we have decided that debian is the image we are
copying. The message is misleading when copycds is run for non
ubuntu/debian OSes
