>Description:
Additional swap partition on an attached USB drive specified in /etc/fstab will not be mounted properly at boot.
>How-To-Repeat:
Create a swap partition on a USB drive, eg. /dev/sd1b & add an entry to this swap partition to /etc/fstab:

/dev/sd1b none swap sw 0 0

Leave the USB drive attached & reboot.

The order of initialization is:
0.  run swapctl -A
1.  mount other partitions defined in /etc/fstab & check via fsck
2.  detect USB devices

Other kinds of partitions on a USB drive can be specified in /etc/fstab, & successfully mounted by adding the following to /etc/rc.conf.d/fsck:

start_precmd=fsck_precmd
fsck_precmd() {
    n=60
    echo "delaying fsck for $n seconds..."
    sleep $n
}

...which delays the actions of fsck long enough for all USB devices to be detected.

I cannot find an equivalent manner of delaying swapctl.
>Fix:
Remove the USB swap partition entry from /etc/fstab & add manually through swapctl -a /dev/sd1b.

      Try putting the above lines into /etc/rc.conf.d/swap1.

 $ cd /etc/rc.conf.d
 $ ls -l
 total 4
 -rw-r--r--  1 root  wheel  120 Sep 13 14:57 fsck
 -rw-r--r--  1 root  wheel  117 Sep 20 13:57 swap1
 $ cat swap1
 start_precmd=swapctl_precmd
 swapctl_precmd() {
     n=60
     echo "delaying swapctl for $n seconds..."
     sleep $n
 }
 $

 After creating the above file & rebooting, I see the same errant
 behavior.  During initialization, the following messages scroll by
 before fsck checks all partitions defined in /etc/fstab.

 swapctl: adding /dev/sd0b as swap device at priority 0
 swapctl: /dev/sd1b: Device not configured

 Yes, I can manually add the swap partition later through swapctl -a,
 but the fundamental question still remains as to how to delay swapctl
 initially as I can with fsck.

 Do you see your custom "delaying swapctl for 60 seconds..." message?

 No.

 Renaming the script to "swap" does delay swapctl from adding swap
 partitions until all USB devices have been detected.  Afterwards, all
 swap partitions defined in /etc/fstab appear initialized:

 $ swapctl -l
 Device      512-blocks     Used    Avail Capacity  Priority
 /dev/sd0b      4096150    10528  4085622     0%    0
 /dev/sd1b      2048000    10592  2037408     1%    0
 Total          6144150    21120  6123030     0%
 $

 Tangentially, I also see the following messages at the end of the
 boot-time initializations:

 ...

 Clearing /tmp.
 Creating a.out runtime link editor directory cache.
 Checking quotas: done.

 Why is /etc/rc.conf.d/swap being called a second time?

 Thanks.

 Looks like both /etc/rc.d/swap[12] scripts have:

  load_rc_config swap

 I thnk they should be:

 load_rc_config swap1

 and

 load_rc_config swap2

 So either fix those rc.d scripts or name your rc.conf.d script as swap 
 (not swap1).

 In regards to the filename change in my last email:

 -------
 src/etc/rc.d/swap2 revision 1.4
 date: 2000-07-17 05:27:04 -0700;  author: lukem;  state: Exp;  lines: +2 -2;
 use "load_rc_config swap" for swap1 and swap2
 -------

 I don't know why though ...

 Ask lukem (per my comment in the previous email).

 I think this should be fixed like you see.

USB disk detection is generally handled before mountroot now days, so
this should also be fixed.  also, reported against 4.0.
