This reverts commit 3d342f72a7.
This is causing trouble for macOS users. Also it's painfully slow
compared to using the sudo method. This should definitely not be
the default since it punishes people who have genext2fs installed.
Warnings fixed:
* SC2086: Double quote to prevent globbing and word splitting.
* SC2006: Use $(...) notation instead of legacy backticked `...`
* SC2039: In POSIX sh, echo flags are undefined
* SC2209: Use var=$(command) to assign output (or quote to assign string)
* SC2164: Use 'cd ... || exit' or 'cd ... || return' in case cd fails
* SC2166: Prefer [ p ] && [ q ] as [ p -a q ] is not well defined.
* SC2034: i appears unused. Verify use (or export if used externally)
* SC2046: Quote this to prevent word splitting.
* SC2236: Use -z instead of ! -n.
There are still a lot of warnings in Kernel/run about:
- SC2086: Double quote to prevent globbing and word splitting.
However, splitting on space is intentional in this case, and not trivial to
change. Therefore ignore the warning for now - but we should fix this in
the future.
Ports/.port_include.sh, Toolchain/BuildIt.sh, Toolchain/UseIt.sh
have been left largely untouched due to use of Bash-exclusive
functions and variables such as $BASH_SOURCE, pushd and popd.
This removes grub and all the loopback device business from the default
build process. Running grub takes about a second, and it turns out it's
inconsistently packaged in different distributions, which has led to
at least one confusing issue so far (grub-install vs grub2-install).
Removing it from the basic path will make it easier for people to try
Serenity out.
There are now two scripts that can be used to build a disk image:
1. `build-image-grub.sh` - this will build an image suitable for writing
to the IDE hard drive of a physical machine, complete with a partition
table and bootloader. This can be run in qemu with the `qgrub` target
for the `run` script.
2. `build-image-qemu.sh` - this is a simpler script which creates a bare
filesystem image rather than a full MBR disk.
Both of these call out to `build-root-filesystem.sh` to do most of the
work setting up... the root filesystem.
For completeness' sake, I've retained the `sync.sh` script as a simple
forwarding to `build-image-qemu.sh`.
This relies on the functionality from #194 and #195. #195 allows us to
use `/dev/hda` as the root device when nothing else is specified, and #194
works around a strange feature of qemu that appends a space to the kernel
command line.
