helper functions
|
|
================
|
|
These functions focus on the installation of devuan directly to disk using the zfs filesystem as the root fs.
|
|
|
|
you can find these blend helper functions in `blends/${blend_name}/helpers`.
|
|
|
|
additional or overridden helper functions to add or test functionality or workarounds
|
|
specific to the blend to avoid changes to the sdk.
|
|
|
|
|
|
## build_metal_dist()
|
|
defines the sequence of calls that will result in a devuan install with root and boot zfs to one or two disks (mirrored)
|
|
using either grub-pc or grub-efi to boot.
|
|
|
|
|
|
## blend_bootstrap_setup()
|
|
* Overide the post 'debootstrap stage 2' placeholder function of zlib/debootstrap bootstrap_complete_base.
|
|
* The default is return 0
|
|
|
|
## install-custdebs()
|
|
Override the helper function:
|
|
* takes the 'apt-get -f' out of the loop so that dependency provided by other debs can be resolved.
|
|
* inside the loop it just uninstalls the deb because of unfullfilled deps.
|
|
|
|
## install-deb-from-dsc() : WIP
|
|
* In the style of install-custdebs above but building from the source package using dsc
|
|
* takes a list of package names, looks up the corresponding dsc using it to build and install.
|
|
|
|
## install-deb-from-git_gbp() : WIP
|
|
* take a list of package names and for each select the appropriate salsa/devuan git repo
|
|
* pull in sources, build using gbp
|
|
* place the resulting debs in the custdebs location.
|
|
|
|
## install-custscripts()
|
|
Added function:
|
|
* In the style of install-custdebs above but for a collection of arbitrary scripts placed in a
|
|
* directory alongside the blend custom debs called automate.
|
|
* The scripts are copied from the blends scripts directory to extra/custom-scripts in blend_preinst() above.
|
|
* Called after install-customdebs because some need checkinstall which disappears from archives.
|
|
|
|
## add-user()
|
|
Override the helper function:
|
|
* Allow an alternative skel directory
|
|
|
|
## enable_apt-proxy()
|
|
## disable_apt-proxy()
|
|
|
|
## bootstrap_cpio_unpack()
|
|
Overide the sdk version of this function to prevent deletion prior to unpacking the cpio as we have mountpoints in place.
|
|
|
|
## image_partition_disk_zfs()
|
|
* partition available disks using sgdisk
|
|
|
|
## image_format_partitions_zfs()
|
|
* format the efi partions to fat32
|
|
* make the swap partitions
|
|
* create the zfs root and boot pools
|
|
|
|
## use_swap_partition()
|
|
* calls swapon on the new swap partitions
|
|
|
|
## image_zfs_mount()
|
|
* mounts the zfs pools to the bootstrap directory
|
|
* mounts the efi partition to the bootstrap /boot
|
|
* mounts dev proc and sys
|
|
|
|
## image_zfs_umount()
|
|
* the reverse of image_zfs_mount
|
|
|
|
## get_selections()
|
|
* gets dpkg selections and places three files in /var/tmp:
|
|
* /var/tmp/packages.list
|
|
* /var/tmp/pkgs_auto.lst
|
|
* /var/tmp/pkgs_manual.lst
|
|
|
|
## set_selections()
|
|
uses three files to replicate the installed packages of another system.
|
|
* /var/tmp/packages.list
|
|
* /var/tmp/pkgs_auto.lst
|
|
* /var/tmp/pkgs_manual.lst
|
|
|
|
## enablessh()
|
|
this function will allow a root or user login in the bootstrapped root using:
|
|
* ssh-copy-id default@192.168.1.x
|
|
|
|
|
|
## install_kernel_headers()
|
