/boot/grub not mounted by fstab, mountpoint on bpool not available
|

------
|
||
change /tmp to tmpfs
|
||
------
|
||
rewrite the docker helpers that just set config in apt-conf.d to the sysconf pattern.
|
||
|
||
1. a heredoc that doesn't redirect to a file with function names of the form:
|
||
conf_print_<NAME>()
|
||
2. a line to direct the print function to a file of the form:
|
||
conf_print_fstab | sudo tee "$strapdir/etc/fstab" >/dev/null
|
||
|
||
----------------
|
||
Move the docker blend and associated files into its own blend directory.
|
||
Move the metal blend and associated file into its own blend directory.
|
||
|
||
add submodules, dockerfile and gitlab-ci.yml so that images can be build automatically.
|
||
|
||
---------------------
|
||
|
||
debootstrap has the option 'doing_variant' that accepts
|
||
1. minbase - base="$devuan_required apt"
|
||
2. buildd - base="$devuan_required apt build-essential"
|
||
3. fakechroot - base="$devuan_required $(get_debs Priority: important)" required="$required binutils"
|
||
4. - base="$devuan_required $(get_debs Priority: important)"
|
||
|
||
To get the packages involved:
|
||
dpkg-query -f '${binary:Package} ${Priority}\n' -W | grep -w 'required\|important'
|
||
|
||
|
||
so we would have to override lib/libdevuansdk/zlibs/bootstrap to:
|
||
1. add --variant or
|
||
2. change the --includes to be a list in config debootstrap_includes+=() to reflect the changes above and allow for other variant at the debootstrap stage.
|
||
3. set equivalent groupings in blend $release/config $base_packages and have them applied after debootstrap.
|
||
|
||
debootstrap/scripts/ceres also has
|
||
case $MIRRORS in
|
||
https://*)
|
||
base="$base apt-transport-https ca-certificates"
|
||
;;
|
||
esac
|
||
|
||
But not for other apt-transports like apt-transport-tor
|
||
case $MIRRORS in
|
||
https://*)
|
||
base="$base apt-transport-https ca-certificates"
|
||
;;

If you are going to install packages into the running livesd before a get-selections it would make sense to save the results of a diff on /home/default in the overlay to capture and configuration that you may choose to do as well as a debconf-get-selections for any settings chosen during install.
|
||

|
||
|
||
1. image_partition_disk_zfs can have two more options to fit the openzfs instructions:
|
||
i. bios v uefi (we do both)
|
||
a. Run this if you need legacy (BIOS) booting:
|
||
sgdisk -a1 -n1:24K:+1000K -t1:EF02 $DISK
|
||
|
||
b. Run this for UEFI booting (for use now or in the future):
|
||
sgdisk -n2:1M:+512M -t2:EF00 $DISK
|
||
|
||
ii. Unencrypted v encrypted (is zfs native encryption performant yet?)
|
||
a. Unencrypted or ZFS native encryption:
|
||
sgdisk -n4:0:0 -t4:BF00 $DISK
|
||
|
||
b. LUKS:
|
||
sgdisk -n4:0:0 -t4:8309 $DISK
|
||
|
||
2. raid as specified by type, so far we have mirror or none/striped but we do have available disks list so we could add raidz, raidz2, or raidz3 adding tests for the correct number of disks needed for each.
