Please tell me if copy can preserve symbolic links, already created on
part2, part3 (for data) ?
2. Using:
to copy the partition of one stick to another will preserve symbolic links.
3. The USB stick evidently does not need to be bootable it is simply adding writable storage to the Linux already installed in the router.
4. Using a USB stick for swap on a system that has enough memory such that it does not use swap is okay is it not? This is assuming Linux is like Solaris and does keep a copy of memory in swap all the time but only:
1. Uses swap when the OS is actually low on memory.
2. Swap out a process in memory has not been used for a long time (in which case it will get swapped out but may not need swapping back in if the copy in memory is still resident)?

SCO 5.07: How do I copy files to a USB memory stick?
The stick is formatted as a hd and has an active Unix partition using the hole stick for Unix.
How do I get acces to the stick? (1 Reply)

Dummies questions, perfect for this. I cannot mount my idiotic usb stick on Slackware, I input the following on non-graphic mode as root:
Mount -t vfat /dev/sdc1/usbstick
usbstick is the folder i created for mounting my USB, the file system is FAT, and everytime I input that I get some kind... (2 Replies)
When mounting a USB stick or pen drive on a FreeBSD machine I always issue the following command:
mount -t msdosfs /dev/da0s1 /mnt
Something I have always wondered is what the option msdosfs stands for and more importantly, why it is necessary. (7 Replies)
Hey Guys
I have an Ubuntu CD and I was thinking of creating like a bootable hard drive with various OS so that I can just boot OSs with t drive and not require the CDs. I was just wondering is there a way I can do this, like have Ubuntu boot from a USB stick? If yes how is that possible(even if I... (3 Replies)

I am trying to use a USB (Pen?) drive on Unixware 7.1.4.
The USB stick is in the machine and the machine recognises it when I enter usbprobe as follows:
Path - Address Description

allkmem
mem(7D) Devices mem(7D)NAME
mem, kmem, allkmem - physical or virtual memory access
SYNOPSIS
/dev/mem
/dev/kmem
/dev/allkmem
DESCRIPTION
The file /dev/mem is a special file that provides access to the physical memory of the computer.
The file /dev/kmem is a special file that provides access to the virtual address space of the operating system kernel, excluding memory
that is associated with an I/O device.
The file /dev/allkmem is a special file that provides access to the virtual address space of the operating system kernel, including memory
that is associated with an I/O device. You can use any of these devices to examine and modify the system.
Byte addresses in /dev/mem are interpreted as physical memory addresses. Byte addresses in /dev/kmem and /dev/allkmem are interpreted as
kernel virtual memory addresses. A reference to a non-existent location returns an error. See ERRORS for more information.
The file /dev/mem accesses physical memory; the size of the file is equal to the amount of physical memory in the computer. This size may
be larger than 4GB on a system running the 32-bit operating environment. In this case, you can access memory beyond 4GB using a series of
read(2) and write(2) calls, a pread64() or pwrite64() call, or a combination of llseek(2) and read(2) or write(2).
ERRORS
EFAULT Occurs when trying to write(2) a read-only location (allkmem), read(2) a write-only location (allkmem), or read(2) or
write(2) a non-existent or unimplemented location (mem, kmem, allkmem).
EIO Occurs when trying to read(2) or write(2) a memory location that is associated with an I/O device using the /dev/kmem spe-
cial file.
ENXIO Results from attempting to mmap(2) a non-existent physical (mem) or virtual (kmem, allkmem) memory address.
FILES
/dev/mem Provides access to the computer's physical memory.
/dev/kmem Provides access to the virtual address space of the operating system kernel, excluding memory that is associated with an
I/O device.
/dev/allkmem Provides access to the virtual address space of the operating system kernel, including memory that is associated with an
I/O device.
SEE ALSO llseek(2), mmap(2), read(2), write(2)WARNINGS
Using these devices to modify (that is, write to) the address space of a live running operating system or to modify the state of a
hardware device is extremely dangerous and may result in a system panic if kernel data structures are damaged or if device state is
changed.
