Title: nozswap question
Post by: paskali on June 03, 2013, 05:19:05 PM

Hi all, i have a simple question about the boot option code "nozswap".
I boot my tiny core linux by lilo on a sistem with 768Mb of ram and a swap file of 384Mb.
As follow:

Code: [Select]

boot = /dev/sda
root = /dev/sda3
lba32
compact
prompt
timeout = 300
vga = 773
initrd = /boot/core.gz
read-only
image = /boot/vmlinuz
  label = Normal
  append = "tce=sda1 waitusb=0 swapfile=sda2 home=sda2 opt=sda2 norestore kmaps=qwerty/us-acentos
noswap nodhcp noutc host=zemir tz=CET-1CEST,M3.5.0,M10.5.0/3 user=paskali laptop nozswap multivt
acpi_backlight=vendor quiet"
image = /boot/vmlinuz
label = Embed
append = "waitusb=0 base norestore superuser noswap nodhcp noutc tz=CET-1CEST,M3.5.0,M10.5.0/3
embed laptop nozswap multivt acpi_backlight=vendor quiet"
image = /boot/vmlinuz
label = Restore
append = "tce=sda1 restore=sda1 waitusb=0 swapfile=sda2 home=sda2 opt=sda2
kmaps=qwerty/us-acentos noswap nodhcp noutc host=zemir tz=CET-1CEST,M3.5.0,M10.5.0/3 user=paskali
laptop nozswap multivt acpi_backlight=vendor quiet"
other = /dev/sda1
        label = FreeDOS As well as you see, i select "nozswap" boot option.
My question is simple:
Can i get any sort of advantage by omitting this boot code?

The only advantage would be faster swapping, but this will be at the expense of RAM.
I see absolutely no reason for waitusb=0.

And I see no reason for noswap.

Ok thanks, i have guessed that.
This configuration i have copy and paste from an old system with a previous tinycore version in which i did have some problem with my usb pendrive modem and that i have solved, strangely, with waitusb=0;
as well as i did have problems with a pcmcia usb port adding card.
of course, noswap should be useless, but i do not know if it makes the boot process more quickly by avoiding to scan swap partition.
May be swapfile code is equivalent in the my case.

Boot with the  noswap  code. Then enter:

Code: [Select]

sudo /sbin/swapon -aat the command line and judge for yourself if you think it takes too long.

I do not have swap partition on my computer; i have made an empty file on my ext2 linux partition (in which i have opt, home and boot directories only)

Code: [Select]

sudo dd if=/dev/zero of=tc.swp bs=1M count=384
then i have made:

Code: [Select]

sudo mkswap tc.swp
I have noticed that lilo shows an error if i boot (from dos with linld or loadlin) without nozswap and/or noswap when i try to install it on mbr.

I dislike grub, i do not know to use it and i do not really want to learn that. I have always used lilo and i always will use it.

Point taken, I didn't think that far, noswap cannot harm, disregard my comment above please.
