Yes. There are specialized distros for that purpose - a regular distro would quickly kill the flash drive with write operations. /Per -- Per Jessen, Zürich (11.2°C) -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Not modern flash. Especially not if connected via USB 2.0. Writing continuously at full USB 2.0 speeds, it will take nearly a decade to wear out a 1G drive that does wear-leveling. I still recommend against swap on flash, and there are a number of things you might want to do to minimize writes (relatime or noatime come to mind), but they tends to have their own disadvantages. -- Boyd Stephen Smith Jr. ,= ,-_-. =. bss@iguanasuicide.net ((_/)o o(\_)) ICQ: 514984 YM/AIM: DaTwinkDaddy `-'(. .)`-' http://iguanasuicide.net/ \_/

No, you can use swap without problems. It may be very useful, if you want suspend to disk and use tmpfs for /tmp and possibly /var/tmp and it is possible RAM size is too small for the tmps drives in some situations. Then having a swap can be useful. If you want to reduce the use of the swap parition, you can use a low value (0-10) for /proc/sys/vm/swappiness.

Is that commonly found in plain 8-16G USB flash sticks? /Per -- Per Jessen, Zürich (11.4°C) -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Yes. It's found in virtually every flash device that's been manufactured for a number of years. It's the only way to make them have a reasonable lifetime when they are using a FAT file system (or, really, most non-mtd-device specific file systems). If your device supports full USB 2.0 speeds, it probably has wear-leveling. -- Boyd Stephen Smith Jr. ,= ,-_-. =. bss@iguanasuicide.net ((_/)o o(\_)) ICQ: 514984 YM/AIM: DaTwinkDaddy `-'(. .)`-' http://iguanasuicide.net/ \_/

Thanks - I have a firewall I might just be switching to run on a flash stick. /Per -- Per Jessen, Zürich (14.9°C) -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

You can have it mount RO, and send syslog to another computer. - -- Cheers, Carlos E.

Yeah, but when flash sticks are that durable, I don't need any special setup at all. /Per -- Per Jessen, Zürich (11.5°C) -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
