Local Functions

local activated -> list <map <symbol, string> >

List of mounted partitions, activated swap partitions and loop devices. Amongst other things used for reversing action if mode is changed from update to new installation or if root partition for update is changed. The order of the list if of paramount importance.

Each item is list [string value, string type [, string device]] where:

Keys/values are:

`type The type, one of "mount", "swap" or "loop".

`device The device.

local sdb -> string

Link to SDB article concerning renaming of devices.

global GetInfoOfSelected (symbol what) -> string

Get the key what of the selected root partition.

Parameters:
what
global SetSelectedToValid () -> void

Set the selected root partition to some valid one. Only make sense if the number of valid root partition is one.

local AddToTargetMap () -> void

local RemoveFromTargetMap () -> void

global UnmountPartitions (boolean keep_in_target) -> void

Unmount all mounted partitions, deactivate swaps, detach loopback devices. Uses list activated to make actions in reverse order.

Parameters:
keep_in_target
local AddMountedPartition (map <symbol, string> partinfo) -> void

Add information about mounted partition to internal list.

Parameters:
partinfo partinfo has to be list with exactly two strings, see description of list "activated"
local FSCKPartition (string partition) -> void

Check the filesystem of a partition.

Parameters:
partition
local MountPartition (string mount_point, string device, string mount_type) -> string

Mount partition on specified mount point

Parameters:
mount_point string mount point to monut the partition at
device string device to mount
mount_type string filesystem type to be specified while mounting
Return value:
nil on success, error description on fail
local FsckAndMount (string mount_point, string device, string mount_type) -> string

Check filesystem on a partition and mount the partition on specified mount point

Parameters:
mount_point string mount point to monut the partition at
device string device to mount
mount_type string filesystem type to be specified while mounting
Return value:
nil on success, error description on fail
local check_root_device (string partition, list <map> fstab, string& found_partition) -> boolean

Check that the root filesystem in fstab has the correct device.

Parameters:
partition
fstab
found_partition
local FindPartitionInFstab (list<map> fstab, string mountpoint) -> string

Find a monut poing in fstab

Parameters:
fstab a list of fstab entries
mountpoint string a mount point to find
Return value:
the found partition
local TranslateFSTab (list <map> fstab) -> list <map>

Parameters:
fstab
local read_fstab_and_cryptotab (list <map>& fstab, list <map>& crtab) -> boolean

Parameters:
fstab
crtab
local PrepareCryptoTab (list <map> crtab, list <map>& fstab) -> boolean

Parameters:
crtab
fstab
local IsMounted (string mountpoint) -> boolean

Check if specified mount point is mounted

Parameters:
mountpoint the mount point to be checked
Return value:
true if it is mounted
local MountFSTab (list <map> fstab, string& message) -> boolean

Parameters:
fstab
message
local MountVarPartition (string device) -> string

Mount /var partition

Parameters:
device string device holding the /var subtree
Return value:
nil on success, error description on fail
local MountVarIfRequired (list <map> fstab, string root_device_current) -> string

Check if /var partition is needed, mount it if it is

Parameters:
fstab a list of fstab entries
root_device_current string current root device
Return value:
nil on success, error description on fail
global MountPartitions (string root_device_current) -> boolean

Mounting root-partition; reading fstab and mounting read partitions

Parameters:
root_device_current
local GetArchOfELF (string filename) -> string

Get architecture of an elf file.

Parameters:
filename
local CheckPartition (map partition) -> map

Check a root partition and return map with infomations (see variable rootPartitions).

Parameters:
partition
global FindRootPartitions () -> void

Find all valid root partitions and place the result in rootPartitions. The partitions are mounted and unmounted again (to Installation::destdir). Loads a bunch of kernel modules.
