Right ...  8^°
Sorry, my bad.

Yes, update-rc.d uses the INIT INFO fields and is mandatory when adding a script to /etc/init.d.

No, not me. 8^D!
I'm just an interested observer.

That would be one of the admins (@golinux / @fsmithred / @Ralph.Ronnquist).
But I don't know what the process is / entails.

Thanks for doing that for the team Dev1.

Yes, I saw it.

But this is for an undepowered (Intel Atom N280/2Gb) ca. 2009 netbook for which I need a simple/easy solution.
The zramctl command can set up all the parameters I need in a jiffy in case the default ones are not suitable or I want to experiment.

Thanks for your input.

No need.

In true (and time proven) Linux fashion I found a way out.
ie: by doing it in a different manner.

For those interested, the whole explanation is here.

TL;DR
For whatever reason, it seems the problem of getting the/a zram script to start in /etc/init.d has been doing the rounds for a while.
I could not find out why.

The solution is to start zram, setting the parameters and the zramswap file directly from rc.local.
And Bob's your uncle.

To test, I just dropped in the lines posted but (just to be neat) I'll write up a short script as a replacement for that.

Still working on my Asus 1000HE. 8^°

I have set up zram / zramswap with this script which I found referenced here.

Just in case, I added both the shebang (#!/bin/sh) and the usual PATH= variable as I saw it was missing.
I then named it zramswap, copied it to /etc/init.d, made it executable and did update-rc.d zramswap defaults.

The problem I have is that it does not start at boot and I can't figure out why.

But I can start it from a terminal:

$ sudo zramswap start
Setting up swapspace version 1, size = 1002.6 MiB (1051303936 bytes)
no label, UUID=05decff9-d90e-4db3-ae9d-a65484a3462c
$ 

$ sudo swapon -s
Filename				Type		Size	Used	Priority
/dev/sda5                              	partition	12595196	0	1
/dev/zram0                             	partition	1026664	0	20
~$ 

$ cat /proc/swaps
Filename				Type		Size		Used		Priority
/dev/sda5                               partition	12595196	0		1
/dev/zram0                              partition	1026664		0		20
$  

$ sudo zramctl
NAME       ALGORITHM DISKSIZE DATA COMPR TOTAL STREAMS MOUNTPOINT
/dev/zram0 lzo-rle    1002.6M   4K   74B    4K       2 [SWAP]
$ 

I can't get anything from running the script in a terminal either:

# /etc/init.d/zramswap start > /tmp/zramswap.log 2>&1
#
# cat /tmp/zramswap.log
#                           <- nothing to see here ...

Just in case ...

#!/bin/sh
#!/usr/bin/env /lib/init/init-d-script

}

	$DAEMON status
}

do_restart_override() {
	if _is_active; then
		$DAEMON restart
	else
		$DAEMON start
	fi
}

How to troubleshoot this further?

Thanks in advance.
