Correct. It does not on regpatch, afaik.

Won't work. See below.

Actually, the reason this doesn't work is that -F loads a registry hive,
not a full registry and .reg files only work on a full registry.

If you load a hive with -F you cannot patch it.

A simple python script will work, however.. something like this:

from samba import registry
import samba.getopt as options

# Open the hive
lp = sambaopts.get_loadparm()
creds = credopts.get_credentials(lp)
hive = registry.open_hive(hivepath, lp_ctx=lp, credentials=creds)

# Mount the hive to HKEY_CURRENT_USER
reg = registry.Registry()
reg.mount_hive(hive, registry.HKEY_CURRENT_USER)
