• Product: Portage Development
• Status: UNCONFIRMED ---

[Description Thomas 2020-12-07 16:39:49 UTC]

If /usr/portage includes mount points, emerge-webrsync will exaust errors for them, because it cant delete them:

Reproducible: Always

Steps to Reproduce:
1. Install gentoo, configure, have some directories within /usr/portage mounted
2. Call "emerge-webrsync"
Actual Results:  
rsync will exaust warnings for every mounted directory, because it cant delete it, or set timestamps

Expected Results:  
Should not mumble about mounted directories not able to delete. It should not touch them at all.

This would be useful to be fixed, because it silences an errorless emerge-webrsync run. It is not an error not being able to delete a mountpoint.

This is what emerge-webrsync does:

local rsync_opts="${PORTAGE_RSYNC_OPTS} ${PORTAGE_RSYNC_EXTRA_OPTS}"

Can you try setting PORTAGE_RSYNC_EXTRA_OPTS="--one-file-system" in make.conf to see if that helps?
