Michael Stapelberg f16a76357f update: use crc32 for checksumming when the client requests it 
This is significantly faster than sha256 on the Raspberry Pi 4:
update speeds increase from ≈12 MB/s to ≈55 MB/s.

Michael Stapelberg 32f88999da set HOME=/perm/$basename when starting services 
Previously, HOME was inherited from the environment of the init process, which
has HOME=/ set. Of course, / is not writable on gokrazy, so this change makes
things less strict and should therefore not break any deployments.

Michael Stapelberg f3445e01a9 fix switchRootPartition on non-PARTUUID installations 
The first update always worked, but a subsequent update would not.

To manually switch an installation to PARTUUID, mount its boot partition and
replace the root= kernel parameter in cmdline.txt, like so:

/tmp/breakglass669384965 # mkdir boot
/tmp/breakglass669384965 # mount /dev/mmcblk0p1 boot
/tmp/breakglass669384965 # cat boot/cmdline.txt
console=ttyAMA0,115200 root=/dev/mmcblk0p2 init=/gokrazy/init elevator=deadline rootwait
/tmp/breakglass669384965 # sed -i 's,root=/dev/mmcblk0p,root=PARTUUID=471cad93-0,g' boot/cmdline.txt
/tmp/breakglass669384965 # cat boot/cmdline.txt
console=ttyAMA0,115200 root=PARTUUID=471cad93-02 init=/gokrazy/init elevator=deadline rootwait
/tmp/breakglass669384965 # umount boot
/tmp/breakglass669384965 # reboot

The PARTUUID= for your installation is printed by gokr-packer:
[…]
2020/05/01 10:05:34 write.go:366: writing MBR (LBAs: vmlinuz=51789, cmdline.txt=119561, PARTUUID=471cad93)

Michael Stapelberg 6beb2e16aa implement remote syslog as a platform feature 
To configure, run the following command in an interactive shell (e.g. via
breakglass, or when mounting the permanent partition of the SD card on the
host):

  mkdir /perm/remote_syslog
  echo 10.0.0.76:514 > /perm/remote_syslog/target

I recommend using a (static) IP address for increased reliability, so that
remote syslog works even when DNS does not.

Michael Stapelberg 14287515bc dhcp: switch to github.com/rtr7/dhcp4 
All existing DHCPv4 packages I looked at were unappealing for one reason or

and github.com/mdlayher/raw together, which suffices for our use-case and gives
us more control.

versions, just in case people don’t update both at the same time).

Michael Stapelberg 238bbfa55e init: update listeners when pressing <ENTER> on the serial console 
This is useful when the network doesn’t come up correctly: you can connect a

the serial console and connect to gokrazy via its IPv6 link-local address (to
find the address, use ping6 ff02::1%eth0).
