It would appear so:
open("/usr/share/icons/gnome/48x48/status/dialog-password.png", O_RDONLY|
O_NOATIME) = -1 EPERM (Operation not permitted)
open("/usr/share/icons/gnome/48x48/status/dialog-password.png", O_RDONLY) = 12
read(12,
"\211PNG\r\n\32\n\0\0\0\rIHDR\0\0\0000\0\0\0000\10\6\0\0\0W\2\371"..., 4096) =
2083
close(12) = 0
Which is a bad patterm. O_NOATIME requires CAP_FOWNER and I don't think
graphic programs are supposed to run as root/privileged. So, there seems to be
a misunderstanding of what O_NOATIME is for. It seems to be related to loading
icons. Is there a common library for that?
