If there is a certificate and key in /etc/ssl/gokrazy-web.{pem,key.pem},
the webinterface will serve and redirect to https.

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.

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)

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.

fixes #50

14287515bc dhcp: switch to github.com/rtr7/dhcp4 
All existing DHCPv4 packages I looked at were unappealing for one reason or
another, so we’re now using a little helper to glue github.com/google/gopacket
and github.com/mdlayher/raw together, which suffices for our use-case and gives
us more control.

The KexecFileLoad syscall wrapper and the KEXEC_* constants were added
to golang.org/x/sys/unix. Use them instead of open-coding them.

24c8ad07b5 streamRequestTo: call f.Sync() 
When calling reboot shortly after /update/*, the kernel should flush its cache,
but if you’re not calling reboot, it would be good to persist the data on disk
nevertheless.

c74265523b implement XSRF/CSRF protection for /stop and /restart 
While stopping/restarting processes seems like a nuisance at best, it’s good
style to prevent these attacks.

architecture and demands. See also:
