Hi,
For background in the Debian win32 port see the mailing list archives
[1]. Basically, the only reason the port is allowed by Debian is that it
could run on ReactOS or wine which are both DFSG [2] compliant.
Microsoft Windows, OS/2... aren't DFSG compliant.
I've read [3] that the Debian win32 ports "failed because most unix
software made unforgivable presumptions about file system semantics;
mainly that you could delete files that were in-use, and rename open
files on top of other open files, etc." Is this something that could be
resolved? I'd imagine the Installable File System (IFS) driver would
need to be modified to remember open files, or perhaps something could
intercept calls to an IFS driver? I think this is what some virus
scanners do, and what clamav is missing.
Porting Debian to ReactOS would give ReactOS a huge number of packages.
The BSD ports collection method or gentoo's build systems may be useful
too. All three would probably mean porting some base software though.
Any comments about porting the base of another OS to ros? Packages like
perl, bash, gcc, glibc seem to have native MS Windows ports.
http://packages.debian.org/stable/base/ lists all the various packages
in Debian's base (note some are specific to various ports, and there are
some semi-duplicated packages).
Another advantage of a Debian win32 port using ReactOS would be a really
nice flexible, modular installer (debian-installer or d-i for short).
I've had problems with the ros installer in the past, specifically I
couldn't install on one system without a mouse. It also asked many
questions, couldn't resize partitions... d-i is nice in that it can be
used with about three prompts, has partition resizing, can download
additional modules... I'd suggest checking it out (I feel like I'm
starting to just advertise it). Fwiw, longhorn seems to boot from a CD
to do it's graphical install that is supposed to have file system
resizing.
Can/does ReactOS support ELF? Alex Ionescu said that there's now an ELF
loader [4]. If so, would there be anything special that would need to be
done to run Linux binaries on ReactOS (beyond syscalls and porting
dependencies)? Is there any advantages to the PE format? If ReactOS
could support running Linux binaries it would be an easier sell to port
Debian to ReactOS as it could reuse things that are already compiled for
Debian. I believe the FreeBSD port (kFreeBSD that is) [5] re-uses some
packages compiled for Linux. OTOH, PE would be a nicer way to go so that
some support for MS Windows could be allowed... Or could MS Windows be
made to support ELF? I'm afraid I also don't know much about the coff
format.
