When I now run sandbox -X with the -i flag, I get the following error:

% sandbox -t sandbox_web_t -i /home/bress/.mozilla -w 1672x968 -X firefox     
rsync: failed to set times on "/tmp/.sandbox-bress-gsuEPq/.": Operation not permitted (1)
rsync error: some files/attrs were not transferred (see previous errors) (code 23) at main.c(1042) [sender=3.0.7]
Failed to populate runtime temporary directory
Failed to create runtime temporary directory
zsh: exit 255   sandbox -t sandbox_web_t -i /home/bress/.mozilla -w 1672x968 -X firefox



I still see this even if I run it using the -H and -T options.

I can run firefox every time I try if I remove the -i option.

If I try to run the command a bunch of times, it will work at random sometimes (but probably less than 10% of the time).
