`mke2fs` has a `-d` option that allows to populate the newly created filesystem without needing to temporarily mount it. That allows to use `parted` and `mkfs.ext3` on regular files without needing root access.
* Support specifying the size of the target disk image for qemu
* For bare metal, only pad the image to the next megabyte
* Use truncate() to extend images, instead of writing zeros (faster)
* Return None from get_disk() with nonexistent name
* Leave 1MiB on non-boot disks, or 1GiB on boot disks, unpartitioned
(for proper 4K alignment and to help preserve the srcfs or boot
partition creation)
* Fix qemu invocation when an external.img is not used
* Make -qr work with kernel bootstrap (will need kexec-fiwix fix)
Ensures that when `--external-sources` is used, the build does not require a working internet connection.
`--unshare-net` is always passed for the sysa phase.
- Split out tmpdir logic into a separate entity & add the appropriate
arguments and checks.
- sysb can be removed since there is now no associated logic.
- Move disk/etc logic into tmpdir.py.
- disk to be created (blank disk given to live-bootstrap) (default)
- disk to already exist but sources downloaded within live-bootstrap
- sources to be downloaded outside live-bootstrap (non-blank disk given
to live-bootstrap)
Also migrate sysb to use sys_transfer in QEMU mode also.
Note that this means copy_sysc is now irrelevant. sysc is *always*
sourced from sysa.
- Rename sources to distfiles for clarity.
- Per sys(a/c) distfiles to reduce rootfs.py processing and reduce RAM
usage in sysa.
- Canonicalise early kaem mes/tcc files to kaem script conventions.
- Cleanup unused setup in python.
- Add parts.rst documentation for Linux kernel.
- Completely fix problems caused by new bootstrap, update checksums for
/usr.
- Globalise populate_device_nodes.
- Enable deblobbing.
Now that we have the Linux Kernel built, we move to a full-disk (rather
than initramfs) setup in sysc. However, we cannot assume the seed kernel
has support for mounting hard drives. So, first we need to kexec into
sysb, which is used as a jumping off point to create the hard drive for
sysc.
Additionally, since 2.6.16 does not have support for on-demand initramfs
(initramfs must be built into kernel), we will have to rebuild the linux
kernel within sysb without the initramfs.
All of this process is not performed for chroot mode. Instead, we skip
sysb and jump straight to sysc, copying over appropriate data.
The python scripts have been changed slightly. Each sys* inherits
SysGeneral, which contains various functions which are not specific to
any sys* and simplifies those files. rootfs now also handles sysb and
sysc.
bootstrap.cfg also gives an indication whether we are running in a
chroot to avoid attempting to kexec/mount within a chroot.
