* fstab data structure FstabData is initialized with passno = "-1"
* other initializers are expected to default to that value
* fstab_line_for_data, when encountering a -1 passno, shall apply simple
logic to decide on a passno value to generate
* mount to / or /boot things given passno 1
* other mounts that aren't none given passno 2
* 'none' mounts given passno 0
* callers can override passno - supply a passno value that isn't "-1"
storage_config: return one type: disk action per multipathed disk
Currently extract_storage_config returns one type: disk action
for every member of a multipathed disk and type: partition
actions for each partition of each disk. This works by generating
a type: disk action for each disk and ignoring the block device
data for the /dev/dm-X device for the multipathed disk.
But in groovy+, the udev rule from multipath-tools that has
always attempted to remove the devices nodes for the partitions
of a disk that is a multipath member actually succeeds, and
trying to generate a type: partition action for a partition with
no underlying device node makes things blow up.
Instead, this branch generates type: disk and type: partitions
actions from the /dev/dm-X nodes for the mutipathed disk and its
partitions, and ignores and disks and partitions that are members
of a multipathed disk.
vmtest/centos: handle different paths to grub config
Centos images used to always have grub installed at
/boot/grub/grub.conf. The most recent build of centos70,
centos70/amd64/20210210_01/root-tgz, now has grub conf located at
/boot/grub2/grub.cfg. This patch checks for either path before
running the sed fixup command.
