update: occasionally the reading of /proc/mounts succeeds, and it's:

 open("/proc/mounts", O_RDONLY|O_LARGEFILE) = 3
 fstat64(3, {st_mode=S_IFREG|0444, st_size=0, ...}) = 0
 read(3, "rootfs / rootfs rw 0 0\n/dev/root"..., 4096) = 290
 write(1, "rootfs / rootfs rw 0 0\n/dev/root"..., 290rootfs / rootfs rw 0 0
 /dev/root / ext3 rw,noatime,nodiratime,data=ordered 0 0
 /proc /proc proc rw 0 0
 /proc/bus/usb /proc/bus/usb usbfs rw 0 0
 /sys /sys sysfs rw 0 0
 /dev/devpts /dev/pts devpts rw 0 0
 /dev/sda2 /home ext3 rw,noatime,nodiratime,data=ordered 0 0
 nodev /debug debugfs rw 0 0
 ) = 290
 read(3, "", 4096)                       = 0
 close(3)                                = 0

there's nothing particularly interesting in it. (perhaps debugfs)
