cook pkgdb: provide new mechanism of recharging: IDs contains "old" ID plus timestamp, bundle.tar.lzma contains all "old" recharge files plus files.list.md5 to determine whether to download massive files.list.lzma or not.

Ref:
Unix time
Unix time (also known as POSIX time or erroneously as Epoch time) is a system for describing instants in time, defined as the number of secondsthat have elapsed since 00:00:00 Coordinated Universal Time (UTC), Thursday, 1 January 1970,[1][note 1] not counting leap seconds.[1][2][note 2]It is used widely in Unix-like and many other operating systems and file formats. Due to its handling of leap seconds, it is neither a linear representation of time nor a true representation of UTC.[note 3] Unix time may be checked on most Unix systems by typing
date +%s on the command line.| Example: 1431460917 (ISO 8601:2015-05-12T20:01:57Z) the Unix time when this page was last generated |
Combined date and time representations
| <date>T<time> |
A single point in time can be represented by concatenating a complete date expression, the letter T as a delimiter, and a valid time expression. For example "2007-04-05T14:30".
grus4dos : map --mem option
map --mem option
https://github.com/chenall/grub4dos/blob/master/README_GRUB4DOS.txt#L3136
*** The CDROM emulation (virtualization) ***
*****************************************************************
The CDROM emulation is sometimes called ISO emulation. Here is an example:
map (hd0,0)/myiso.iso (hd32)
map --hook
chainloader (hd32)
boot
if myiso.iso is not contiguous and you have enough memory, add a --mem option:
map --mem (hd0,0)/myiso.iso (hd32)
map --hook
chainloader (hd32)
boot
Note: (hd32) is a grub drive number equivalent to (0xA0). If a virtual drive is
specified with a drive number greater than or equal to 0xA0, then it will be
treated as a cdrom (i.e., with 2048-byte big sectors).
Like normal disk emulations, the CDROM emulation also (mainly) works with
real-mode OSes. After a protected-mode OS kernel (such as
WinNT/2K/XP/VISTA/LINUX) gains control, the OS would have no ability to access
the virtual CDROM through BIOS int13.
DOS/Win9x users may google for ELTORITO.SYS and use it in CONFIG.SYS as a
device driver for the virtual cdrom.
Example usage of eltorito.sys in CONFIG.SYS:
device=eltorito.sys /D:oemcd001
Corresponding MSCDEX command which can be placed in AUTOEXEC.BAT:
MSCDEX /D:oemcd001 /L:D
Due to some bugs found in eltorito.sys, the driver could fail to load. If you
encounter such problems, then you may replace (hd32) with (0xFF) for the
virtual cdrom drive number and try again.
