[systemd-devel] Support for unmerged-usr systems will be REMOVED in the second half of 2023

[TJ]

Just seen this announcement in the v252 changelog:

"We intend to remove support for split-usr (/usr mounted separately 
during boot) ..."

How does this align with support for separate /usr/ with dm-verity ?

For example, this will affect nspawn. See "man 1 systemd-nspawn" and 
"--root-hash=" where in respect of /usr/ it says:

"Note that this configures the root hash for the root file system. Disk 
images may also contain separate file systems for the /usr/ hierarchy, 
which may be Verity protected as well. The root hash for this protection 
may be configured via the "user.verity.usrhash" extended file attribute 
or via a .usrhash file adjacent to the disk image, following the same 
format and logic as for the root hash for the root file system described 
here."
