What else can I help you with?
Which is the Linux kernel image file from the following and what is location in the file system?
The kernel image is the file in /boot that has a name like "vmlinuz" in it.
What is a .ko file in Linux?
The .ko extension is placed on kernel modules (loadable drivers) in Linux. Further, '.ko' extension is called 'kernel Object', and is implemented from kernel 2.6 onwards, this is perhaps the biggest change as far as loadable kernel modules are concerend. For example, the serial device driver that in Linux 2.4 lived in the file 'serial.o' in Linux 2.6 lives in the file 'serial.ko' .
Where is the source to the Linux kernel stored on the file system?
Traditionally in /usr/src/linux.
What is the Linux Virtual File System used for?
The Linux VFS (Virtual File System) may be thought of as a sort of interface between the Linux kernel and the mounted file systems. There can be many different file system types mounted simultaneously and VFS allows the Linux kernel to see and address them all in a similar way. This provides Linux with a great deal of flexibility. [JMH]
Is the NTFS file system supported by Linux?
The NTFS file system is supported in Linux by both a kernel module and several userspace programs. It is not supported as a root file system and is not recommended for permanent file storage.
What are modules in Linux?
Modules are pieces of binary data that can be loaded into the Linux kernel at run time. These are typically drivers for devices or file systems.
How long can the path file length from home in Linux be?
Starting from /home, the path may include up to 4,091 additional characters (that is, Linux supports 4096 characters for the path, with up to 256 characters per file or directory name). This is a limitation of the kernel, and not of the file system. It is technically possible to modify the Linux kernel to support even longer file and path names if a user needed to do so.
What is the mount command in Linux?
The mount command instructs the kernel to access the file system on a partition or device.
What is ldlinux.sys?
ldlinux.sys is the name of the bootloader file used in SYSLINUX and ISOLINUX (used for booting Linux off of FAT32 and ISO9660 filesystems, respectively). It is loaded into memory by the BIOS on bootup. The loader then parses the configuration file (syslinux.cfg or isolinux.cfg) to know which kernel to launch, along with parameters to be passed to it.
What is the library name in which the semaphore.h header file is present in Linux?
semaphore.h is in the kernel source. If you're looking for it for your particular distribution (such as for compiling modules), look in the kernel source package or install the kernel headers.
What is the default file system for Linux?
It matters what file systems you or your distributor build the Linux Kernel to support. Generally EXT2, EXT3, and EXT4 are the defaults. EXT4 is recommend for modern Linux installs. Many other files systems are be supported if built into the kernel FAT (12, 16, and 32), XFS, NTFS (using fuse), and etc.
What Linux utility provides an answer file for unattended installs in Linux?
As 'Linux' is actually the Linux Kernel and a bunch of other tools packaged together as a distro, this will depend on the distro you use. For example, Red Hat Linux uses a file called ks.cfg (known as kickstart) which contains information for it's installer system called Anaconda.
