Made changes to limit the line length in following files for #1986,
- pmb/install/_install.py
- pmb/install/blockdevice.py
- pmb/install/losetup.py
- pmb/install/partition.py
Added the above files in E501 flake8 command list.
Substitute f-string for string concatenation.
Do not go through the pmb.chroot.init() code path when running
pmb.install.losetup.umount() inside pmb.chroot.shutdown(). This is not
necessary, as pmb.install.losetup.umount() only gets called if the
chroot is already initialized and /dev/loop-control is mounted inside
the chroot.
Not going through this code path is important for the upcoming workdir
migration patch. Without this fix, it will fail with the following if
running "pmbootstrap install" before the work migration:
ERROR: Could not figure out on which release channel the 'native' chroot is
While at it, also remove unnecessary "#!/usr/bin/env python3" in files
that only get imported, and adjust other empty/comment lines in the
beginnings of the files for consistency.
This makes files easier to read, and makes the pmbootstrap codebase more
consistent with the build.postmarketos.org codebase.
Adds an optional deviceinfo variable, `deviceinfo_rootfs_image_sector_size`,
which specifies the logical sector size of the device's storage.
Some devices made after 2016 with UFS storage uses 4096 byte sectors
instead of the normal 512 bytes. The partition table in our rootfs
must match, otherwise the root filesystem won't mount on the device.
This change passes the sector size to `losetup` when creating the image
if the deviceinfo specifies it, so the image will have the correct
sector size.
If the deviceinfo doesn't specify the new option, the behaviour
is the same as previous versions of pmbootstrap.
Note that the sector size option only works on Linux 4.14 and above,
so pmbootstrap should be run on a >4.14 computer when installing to
devices with non-standard sector size.
To find if a device needs this parameter, run `fdisk -l` on the device.
If the output shows
`Note: sector size is 4096 (not 512)`
then add `deviceinfo_rootfs_image_sector_size="4096"` to the deviceinfo.
This is needed by the Pixel 3 XL (google-crosshatch) port.

This checks for /sys/modules/loop before modprobing the loop module. My
understanding is that if this module is built into the kernel, that this
directory is still created. For a kernel without loop built in,
losetup.py will try to load the module using modprobe.
Thanks, cmdr2! Here's the text from his PR:
Fixes an issue on alpine-vanilla, where `/dev/loop` is a directory (containing `/dev/loop/0`, `/dev/loop/1` ..etc), and causes `./pmbootstrap install` to fail.
Ignoring the `/dev/loop` directory works because `/dev/` also contains files named `/dev/loop0`, `/dev/loop1` ..etc, which the new code will still pick up.
The `install` command passes after this fix on my alpine-vanilla.
