NAME

sysmerge — upgrade current operating system from a sysroot

SYNOPSIS

sysmerge

[-cfpsw] [-t target] [--booting] [--hook-finalize] [--hook-prepare] source

DESCRIPTION

sysmerge upgrades the current operating system by copying the system files from the specified source directory (usually a sysroot) onto the current root filesystem. This is meant to be used when building the operating system from source as described in development(7). sysmerge installs the system manifest from the tix repository in the source directory, as well as all the ports found. If a full upgrade is done, then all ports not found will be uninstalled. Upgrade hooks will be run if further actions are needed to migrate the system to the new version as described in following-development(7). The initrd(7) is regenerated using update-initrd(8). If grub is enabled in upgrade.conf(5), then the bootloader is reinstalled and reconfigured as needed. sysmerge is an automatic and non-interactive upgrade. It is meant to be used as part of the development process to upgrade to locally built versions. The sysupgrade(8) program is by contrast an interactive program. The options are as follows:

--booting

It's boot time, complete the system upgrade that was delayed. This is meant to be used by init(8) through the merge boot target. This installs the /sysmerge directory onto the root filesystem and removes the /sysmerge directory.

-c, --cancel

Cancel a pending upgrade that would trigger on the next boot. Remove the /sysmerge directory and restore the old kernel(7) and initrd(7).

-f, --full

Full system upgrade that uninstalls ports not present in the source directory.

--hook-finalize

Run the post-upgrade hooks. This is meant to be used by the old sysmerge when it invokes the new sysmerge during a non-waiting upgrade.

--hook-prepare

Run the pre-upgrade hooks. This is meant to be used by the old sysmerge when it invokes the new sysmerge during a non-waiting upgrade.

-s, --system

Upgrade the system. This option is implied unless --ports is passed.

-t, --target=target

Upgrade the installation in the target directory rather than the root filesystem. This option is supported if the target is the / directory or only has ports installed and no system. This option is unsupported if target has the system installed and is not the / directory. Instead one should chroot(8) into the target and run the old sysmerge inside rather than the new sysmerge. However, this option may be useful for repairing installations and should work in practice, however it is untested and might not properly handle incompatible changes across releases.

-p, --ports

Upgrade the ports. This option is implied unless --system is passed.

-w, --wait

Wait until the next boot to complete the upgrade, rather than finishing it now. The upgrade is installed into the /sysmerge directory instead, with the new kernel and initrd files in /boot/sysmerge. The new kernel(7) has a new initrd(7) that runs /sysmerge/sbin/sysmerge --booting on boot through the chain-sysmerge init(8) boot target, which performs the operating system upgrade. The bootloader configuration is regenerated with a menu option to perform the upgrade if grub is enabled in upgrade.conf(5), otherwise the /etc/default/grub.d/10_sortix.cache bootloader fragment can be used to manually bootload the upgrade.
